Rad-hard 16-bit transceiver, 3.3 V to 5 V bidirectional level shifter

Datasheet −production data

Features

■ Fully compatible with 54ACS164245

■ Dual supply bidirectional level shifter

■ Extended voltage range from 2.3 V to 5.5 V

■ Separated enable pin for 3-state output

■ Schmidt-triggered I/Os: 100 mV hysteresis

■ Internal 26 Ω limiting resistor on each I/O

■ High speed: Tpd = 8 ns maximum

■ Bus hold

Ceramic Flat-48

■ Fail safe

■ Cold spare

The upper metallic lid is not electrically connected to

any pins, nor to the IC die inside the package

■ Hermetic package

■ 100 krad (Si) at any Mil1019 dose rate

■ SEL immune to 110MeV.cm /mg LET ions

■ RHA QML-V qualified

All pins have cold spare buffers to change them to

high impedance when V is tied to ground.

Description

This IC is intended for two-way asynchronous

communication between the data buses and the

direction of the data transmission is determined

by the nDIR inputs.

The 54AC164245 is a rad-hard advanced high-

speed CMOS, Schmitt trigger 16-bit bidirectional

multi-purpose transceiver with 3-state outputs and

cold sparing.

The A port interfaces with the 3.3 V bus but can

also operate at 2.3 V. The B port operates with the

5 V bus.

Designed for use as an interface between a 5 V

bus and a 3.3 V bus in mixed 5 V/3.3 V supply

systems, it achieves high-speed operation while

maintaining the CMOS low-power dissipation.
