SN74ABT2244ADBR Description

Short technical summary and product information.

The SN74ABT2244ADBR is an octal non-inverting buffer/line driver designed for high-performance bus-oriented systems. It provides eight independent non-inverting buffer channels with 3-state outputs, controlled by two output enable pins (1OE and 2OE).

 

The device operates from a 4.5V to 5.5V supply voltage, making it suitable for standard 5V logic systems. Each output can sink up to 12mA and source up to -32mA, enabling direct drive of heavily loaded buses. Maximum supply current is 30mA.

 

This buffer is built using Texas Instruments' advanced BiCMOS (ABT) technology, offering low noise and high drive capability. It is specified for an industrial temperature range of -40°C to 85°C, ensuring reliable operation in harsh environments. The part is housed in a 20-pin SSOP (Shrink Small Outline Package) for space-constrained applications.
