DESCRIPTION

The 16-bit wide UT54ACS162245S MultiPurpose low voltage

transceiver is built using Aeroflex UTMC’s Commercial

RadHard

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

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

and ground all V

COLD/WARM SPARE FUNCTION

The device will place all outputs into a high-impedance state if

either V

supply is taken to zero volts (I

, warm spare), or

if both V

supplies are set to zero volts (I

, 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
