DESCRIPTION
The 16-bit wide UT54ACS162245S MultiPurpose low voltage
transceiver is built using Aeroflex UTMC’s Commercial
RadHard
TM
epitaxial CMOS technology and is ideal for space
applications. This high speed, low power UT54ACS162245S
low voltage transceiver is designed to perform multiple func-
tions including: asynchronous two-way communication,
Schmitt input buffering, voltage translation, warm and cold spar-
ing. With V
DD
equal to zero volts, the UT54ACS162245S out-
puts and inputs present a minimum impedance of 1MΩ making
it ideal for "cold spare" applications. Balanced outputs and low
"on" output impedance make the UT54ACS162245S well suited
for driving high capacitance loads and low impedance back-
planes. The UT54ACS162245S enables system designers to in-
terface 2.5 volt CMOS compatible components with 3.3 volt
CMOS components. For voltage translation, the A port interfac-
es with the 2.5 volt bus; the B port interfaces with the 3.3 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.

is at 2.5 volts, either 2.5 or 3.3 volts CMOS logic
levels can be applied to all control inputs. For proper operation
connect power to all V

or V
SS
input pins). Tie unused inputs to V

COLD/WARM SPARE FUNCTION
The device will place all outputs into a high-impedance state if
either V
DD
supply is taken to zero volts (I
WS
, warm spare), or
if both V
DD
supplies are set to zero volts (I
CS
, cold spare).
DEVICE POWER UP FUNCTION
The device will place all outputs into a high-impedance during
power-up. The high impedance state is maintained for a time
period approximately equal to the rise time of V
DD1
.
