RadHard Schmitt CMOS 16-bit Bidirectional MultiPurpose Transceiver

Datasheet

FEATURES

DESCRIPTION

The 16-bit wide UT54ACS164245S MultiPurpose transceiver

is built using UTMC’s Commercial RadHard

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 V

outputs and inputs present a minimum impedance of 1M

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.
