Overview
The 74LVC245APW-Q100 is an 8-bit bus transceiver with 3-state outputs, manufactured by Nexperia (previously part of NXP USA Inc.). This device is designed for high-performance and low-power applications, particularly in automotive and industrial environments. It features an output enable (OE) and a send/receive (DIR) input for direction control, allowing for flexible data transmission between two buses. The device is fully specified for partial power-down applications using IOFF circuitry, which prevents backflow current when the device is powered down.
