SN74ACT244PW Description

Short technical summary and product information.

The SN74ACT244PW from Texas Instruments is an active eight-channel buffer designed for improved performance and density in applications like memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This device features TTL-compatible CMOS inputs and three-state outputs, operating within a voltage range of 4.5V to 5.5V.

 

Key electrical characteristics include a maximum propagation delay (tpd) of 9.5ns at 5V, a low supply current of 40µA, and output drive currents of 24mA for both IOL and IOH. The buffer is non-inverting and organized as two 4-bit buffers, each with a separate output-enable (OE) input. When OE is low, data passes from the A inputs to the Y outputs; when OE is high, the outputs enter a high-impedance state.

 

Packaged in a 20-TSSOP, the SN74ACT244PW is suitable for surface mount applications. It operates within a temperature range of -45°C to 125°C. The device includes features such as balanced outputs and input clamp diodes, contributing to its very high speed capability.
