SN74ACT244PWR

The SN74ACT244PWR is an octal buffer/driver with 3-state outputs, designed primarily for driving highly capacitive or relatively low-impedance loads. It is part of the Advanced CMOS (ACT) logic family, which combines low power consumption with high speed. The device features two groups of four buffers each, with each group having its own output enable (OE) control. When the OE is low, the corresponding outputs are enabled, and the device functions as a standard buffer. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the bus. This makes the SN74ACT244PWR ideal for applications requiring bus interfacing or signal buffering.
Key features include TTL-compatible inputs, a wide operating voltage range typically from 4.5V to 5.5V, and a high output drive capability. The device comes in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, denoted by the PWR suffix. Engineered for increased reliability, this buffer/driver is suitable for both commercial and industrial applications, offering robustness and efficiency in data communication or interfacing needs.
