DESCRIPTION
The 16-bit wide UT54ACS164245S MultiPurpose transceiver
is built using UTMC’s Commercial RadHardTM epitaxial
CMOS technology and is ideal for space applications. This high
speed, low power UT54ACS164245S transceiver is designed to
perform multiple functions including: asynchronous two-way
communication, signal buffering, voltage translation, and cold
sparing. With VDD equal to zero volts, the UT54ACS164245S
outputs and inputs present a minimum impedance of 1MΩ mak-
ing it ideal for "cold spare" applications. Balanced outputs and
low "on" output impedance make the UT54ACS164245S well
suited for driving high capacitance loads and low impedance
backplanes. The UT54ACS164245S enables system designers
to interface 3.3 volt CMOS compatible components with 5 volt
CMOS components. For voltage translation, the A port inter-
faces with the 3.3 volt bus; the B port interfaces with the 5 volt
bus. 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.
