The 16-bit wide UT54ACS162245SLV MultiPurpose low voltage transceiver is built using Aeroflex’s epitaxial CMOS technology and is ideal for space applications. This high speed, low power UT54ACS162245SLV low voltage transceiver is designed to perform multiple functions including: asynchronous two-way communication, Schmitt input buffering, voltage translation, warm and cold sparing. With VDD equal to zero volts, the UT54ACS162245SLV outputs and inputs present a minimum
impedance of 1MΩ making it ideal for "cold spare" applications. Balanced outputs and low "on" output impedance make the
 direction control (DIRx) controls the direction of data flow. The output enable (OEx) overrides the direction control and disables both ports. These signals can be driven from either port A or B.  The direction and output enable controls operate these devices as either two independent 8-bit transceivers or one 16-bit transceiver.
