54VCXH162244

Low voltage CMOS 16-bit bus buffer (3-state inverter)

with 3.6V tolerant inputs and outputs

Features

■ 1.65 to 3.6V inputs and outputs

■ High speed:

– t = 3.4ns at V = 3.0 to 3.6V

– t = 3.8ns at V = 2.3 to 2.7V

■ Power down protection on inputs and outputs

■ Symmetrical output impedance:

Flat-48

– |I | = I = 12mA (Min) at V = 3.0V

Description

– |I | = I = 8mA (Min) at V = 2.3V

■ 26Ω serie resistors in outputs

■ Operating voltage range:

The 54VCXH162244 is a low voltage CMOS 16

bit bus buffer (non inverted) 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.

H162244

■ Bus hold provided on data inputs

■ Cold spare function

Any nG output control governs four BUS buffers.

Output Enable input (nG) tied together gives full

16-bit operation.

■ Latch-up performance exceeds

300mA (JESD 17)

■ ESD performance:

When nG is low, the outputs are on. When nG is

HIGH, the output are in high impedance state.

– HBM > 2000V

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

This device is designed to be used with 3 state

memory address drivers, etc. Bus hold on data

inputs is provided in order to eliminate the need

for external pull-up or pull-down resistor.

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

qualification extension undergone)

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

heavy ions irradiation

The device circuits is including 26Ω series

resistance in the outputs. These resistors permit

to reduce line noise in high speed applications.

■ QML qualified product

■ SMD 5962-05210

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

Maximum rating

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
