Overview
The 74LVCH162245ADGG118 is a 16-bit bus transceiver produced by NXP USA Inc., now part of Nexperia. This device is designed for high-speed data transmission and is particularly useful in mixed 3.3 V and 5 V environments. It features two output enables and two send/receive direction inputs, allowing it to function as either two 8-bit transceivers or one 16-bit transceiver. The device is known for its low power consumption, integrated 30 Ω termination resistors, and Schmitt-trigger action at all inputs, making it tolerant of slower input rise and fall times.
