4. Input/Output Voltage Tolerance: Inputs and outputs are 5V tolerant, allowing for interfacing with 5V systems.
5. Latch-Up Performance: Meets or exceeds JEDEC standard JESD-17, with high latch-up performance.
6. Power-Up 3-State: Ensures that outputs remain in high-impedance state during power-up and power-down to prevent bus contention.
7. Wide Operating Temperature Range: Suitable for industrial applications with a range of -40°C to +85°C.
8. Packaging: Available in TSSOP (PW) package for compact designs.
This device is ideal for memory address driving and bus interfacing in high-speed computing applications.
Pinout
Key features include:
- 8 buffer/driver channels.
- 3-state outputs for bus-oriented applications.
- Input and output protection against over-voltage.
Pin configuration:
- Pins 1, 10, 11, and 20 are control pins, including two output enable (OE) pins that are used to enable or disable the outputs.
- Pins 2-9 and 12-19 are data input/output pins, organized in two groups of four (A1-A4, B1-B4).
- The device utilizes two OE pins to potentially control two sets of four output lines independently.
- Pin 5 is typically connected to GND, and pin 14 to Vcc.
This IC is commonly used in applications requiring buffering and signal level translation, thanks to its ability to drive higher loads and its compatibility with TTL input levels.
