54VCXHR162245

Rad hard low voltage CMOS 16-bit bus buffer transceiver

(3-state) with 3.6V tolerant inputs and outputs

Features

■ 1.65 to 3.6V inputs and outputs

■ High speed in both A, B outputs:

– t = 3.4ns at V = 3.0 to 3.6V

– t = 4.3ns at V = 2.3 to 2.7V

■ Symmetrical impedance outputs:

– |I | = I = 12mA (Min) at V = 3.0V

Flat-48

– |I | = I = 8mA (Min) at V = 2.3V

Description

■ Power down protection on inputs and outputs

■ 26Ω serie resistors in bith A and B port outputs

■ Operating voltage range:

The 54VCXHR162245 is a low voltage CMOS 16

bit bus transceiver (3-state) fabricated with sub-

micron silicon gate and five-layer metal wiring

– V (Opr) = 1.65V to 3.6V

C MOS technology. It is ideal for low power and

■ Pin and function compatible with 54 SERIES

very high speed 1.65 to 3.6V applications; it can

be interfaced to 3.6V signal environment for both

inputs and outputs.

HR162245

■ Bus hold provided on both sides

■ Cold spare function

This IC is intended for two-way asynchronous

communication between data buses; the direction

of data transmission is determined by DIR input.

The two enable inputs nG can be used to disable

the device so that the buses are effectively

isolated. The device circuits is including 26Ω

series resistance in the A and B port outputs.

These resistors permit to reduce line noise in high

speed applications. Bus hold on data inputs is

provided in order to eliminate the need for

external pull-up or pull-down resistor.

■ Latch-up performance exceeds

300mA (JESD 17)

■ ESD performance:

– HBM > 2000V

(MIL STD 883 method 3015); MM > 200V

■ 300KRad Mil1019.6 Condition A, (RHA QML

qualification extension undergone)

■ No SEL, no SEU under 72 Mev/cm2/mg LET

heavy ions irradiation

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage. All floating bus terminals during High Z

State must be held HIGH or LOW.

■ QML qualified product

■ Device fully compliant with

DSCC SMD 5962-05213
