SN74LVC245AN Description

The SN74LVC245AN from Texas Instruments is an 8-bit bidirectional transceiver designed for 1.65V to 3.6V voltage operation, making it ideal for mixed-voltage systems. Housed in a 20-pin DIP (Dual In-line Package), this through-hole-mounted device is part of the 74LVC series, known for its low-voltage CMOS technology. It features non-inverting logic and supports bidirectional data flow, enabling seamless communication between buses operating at different voltage levels. With 24mA output drive strength (both high and low), it ensures robust signal integrity in noisy environments. The device is RoHS3 compliant, REACH unaffected, and has an ECCN of EAR99, making it suitable for global applications.
