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 A outputs:

– t = 3.4ns at V = 3.0 to 3.6V

– t = 4.3ns at V = 2.3 to 2.7V

■ Symmetrical impedance A output:

– |I | = I = 12mA (Min) at V = 3.0V

Flat-48

– |I | = I = 8mA (Min) at V = 2.3V

Description

■ High speed B outputs:

– t = 2.5ns (Max) at V = 3.0 to 3.6V

The 54VCXH162245 is a low voltage CMOS 16

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

micron silicon gate and five-layer metal wiring

– t = 3.2ns (Max) at V = 2.3 to 2.7V

■ Symmetrical impedance A output:

– |I | = I = 24mA (Min) at V = 3.0V

C MOS technology. It is ideal for low power and

very high speed 1.65 to 3.6V applications; it can

be interfaced to 3.6V signal environment for both

inputs and outputs.

– |I | = I = 18mA (Min) at V = 2.3V

■ Power down protection on inputs and outputs

■ 26Ω serie resistors in A port output

■ Operating voltage range:

This IC is intended for two-way asynchronous

communication between data buses; the direction

of data transmission is determined by DIR input.

– V (Opr) = 1.65V to 3.6V

■ Pin and function compatible with 54 SERIES

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 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.

H162245

■ Bus hold provided on both sides

■ Cold spare function

■ Latch-up performance exceeds

300mA (JESD 17)

■ ESD performance:

– HBM > 2000V

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.

(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

■ QML qualified product

■ Device fully compliant with

DSCC SMD 5962-02508

Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may

cause permanent damage to the device. These are stress ratings only and operation of the

device at these or any other conditions above those indicated in the Operating sections of

this specification is not implied. Exposure to Absolute Maximum Rating conditions for

extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
