SN74ABT245BMDBREP

SN74ABT245BMDBREP Description

The SN74ABT245BMDBREP is a high-performance, 8-bit bidirectional transceiver from Texas Instruments' 74ABT series, designed for 4.5V to 5.5V voltage supply systems. This surface-mount IC is housed in a 20-pin SSOP package and is available in Tape & Reel (TR) packaging for automated assembly. It features non-inverting logic and supports bidirectional data flow, making it ideal for bus interface applications where voltage translation or signal buffering is required. With 24mA high-output and 32mA low-output current drive, it ensures robust signal integrity in demanding environments. The device is ROHS3 compliant, REACH unaffected, and has a Moisture Sensitivity Level (MSL) of 1, indicating suitability for extended storage and harsh conditions.
