Product overview
The UT54ACS164245SEI is a 16-bit bidirectional transceiver for asynchronous bus communication, signal buffering, and voltage translation. It interfaces 3.3 V and 5 V CMOS buses and uses Schmitt trigger inputs to filter noisy signals. Direction and output-enable controls support either two independent eight-bit transceivers or one 16-bit transceiver. Balanced outputs and low on-state output impedance support capacitive loads and low-impedance backplanes. The device provides cold and warm sparing; the applicable power-supply sequence and operating mode must follow the specific S/SE or SEI datasheet.
