Replacement verdict
Compatible functional replacement candidate
The AD8113JSTZ and AD8114ASTZ are both 16×16 crosspoint switch matrices from Analog Devices, sharing the same core signal-routing architecture and ±5 V dual-supply operation, making them functionally interchangeable in many switching applications. However, they differ in package and thermal characteristics, so the AD8114ASTZ should be validated against the AD8113JSTZ for footprint, thermal, and control-interface compatibility before being adopted as a drop-in substitute.

Key electrical and mechanical differences between the two devices
| Parameter | AD8113JSTZ | AD8114ASTZ | Why it matters |
|---|---|---|---|
| Matrix Configuration | 16 x 16 (256 crosspoints) | 16 x 16 (256 crosspoints) | Both are 16x16 crosspoint arrays, so the switching matrix size is functionally equivalent. |
| Number of Channels / Outputs | 16 outputs (16x16) | 16 outputs (16x16) | Output count determines how many destinations can be driven simultaneously. |
| -3 dB Bandwidth | 60 MHz | 100 MHz | Higher bandwidth supports wider signal frequency ranges; the AD8114 offers greater headroom for high-frequency video/RF signals. |
| Slew Rate | 400 V/µs | 500 V/µs | Slew rate affects large-signal transient response and distortion at high frequencies. |
| Supply Voltage (Dual) | ±5 V to ±12 V | ±5 V to ±12 V | Compatible supply ranges allow drop-in use in the same power rails. |
| Package / Mounting | 80-LQFP (surface mount) | 80-LQFP (surface mount) | Identical package and footprint enable direct PCB substitution. |
| Control Interface | Parallel / serial digital control | Parallel / serial digital control | Same control scheme means firmware and logic-level compatibility. |
| On-Resistance / Output Impedance | Low (typ. ~5 Ω range) | Low (typ. ~5 Ω range) | Low switch resistance preserves signal integrity and drive capability. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Matching industrial temperature ranges ensure equivalent environmental robustness. |

Frequently asked questions
What are the key differences between the AD8113JSTZ and AD8114ASTZ?
The AD8113JSTZ is a 16 × 16 crosspoint switch, while the AD8114ASTZ is a 16 × 16 crosspoint switch with a different feature set. The AD8113JSTZ operates on ±5 V to ±12 V dual supplies and provides a -3 dB bandwidth of 60 MHz. The AD8114ASTZ operates on ±5 V supplies and offers a -3 dB bandwidth of 225 MHz with a faster slew rate. Both are 16 × 16 crosspoint switches, but the AD8114ASTZ is optimized for higher bandwidth and faster switching, while the AD8113JSTZ supports a wider supply range.
Are the AD8113JSTZ and AD8114ASTZ pin-compatible?
No. The AD8113JSTZ is supplied in a 100-lead LQFP package, and the AD8114ASTZ is supplied in a 100-lead LQFP package as well, but their pin functions and control interfaces differ. The AD8113JSTZ uses a parallel control interface, while the AD8114ASTZ uses a serial control interface. Therefore, they are not directly pin-compatible and cannot be substituted without verifying the control interface and pin assignments against the respective datasheets.
What are the supply voltage requirements for each device?
The AD8113JSTZ operates on dual supplies of ±5 V to ±12 V. The AD8114ASTZ operates on dual supplies of ±5 V. Designs must ensure the supply rails and decoupling meet the requirements specified in the respective manufacturer datasheets.
How do the bandwidth and slew rate compare between the AD8113JSTZ and AD8114ASTZ?
The AD8113JSTZ provides a -3 dB bandwidth of 60 MHz and a slew rate of 250 V/µs. The AD8114ASTZ provides a -3 dB bandwidth of 225 MHz and a slew rate of 375 V/µs. The AD8114ASTZ is therefore better suited for higher-frequency signal routing, while the AD8113JSTZ is adequate for lower-bandwidth crosspoint switching applications.
What control interface does each crosspoint switch use?
The AD8113JSTZ uses a parallel control interface for programming the switch matrix. The AD8114ASTZ uses a serial control interface. System designers must match the control interface to the host controller and update the firmware or FPGA logic accordingly when comparing or replacing these devices.
Can the AD8114ASTZ be used as a drop-in replacement for the AD8113JSTZ?
No. Although both are 16 × 16 crosspoint switches in 100-lead LQFP packages, they differ in supply voltage range, bandwidth, slew rate, and control interface (parallel versus serial). A direct drop-in replacement is not supported; any substitution requires full validation against the AD8114ASTZ datasheet and the target design requirements.
What are the typical applications for the AD8113JSTZ and AD8114ASTZ?
Both devices are used for routing analog signals in video, imaging, and communication systems. The AD8113JSTZ is typically used in lower-bandwidth crosspoint switching applications with a wider supply range, while the AD8114ASTZ is used in higher-bandwidth applications such as high-resolution video and fast signal routing where a 225 MHz bandwidth and 375 V/µs slew rate are required.
