74LCX162244

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

with 5V tolerant inputs and outputs

Features

■ 5V tolerant inputs and outputs

■ High speed:

– t = 4.4ns (Max) at V = 3V

■ Power down protection on inputs and outputs

■ Symmetrical output impedance:

TSSOP48

– |I | = I = 12mA (Min) at V = 3V

■ PCI bus levels guaranteed at 12mA

■ Balanced propagation delays:

The 74LCX162244 is a low voltage CMOS 16 bit

bus buffer (non-inverted) fabricated with sub-

micron silicon gate and double-layer metal wiring

■ 26Ω serie resistor in outputs

■ Operating voltage range:

C MOS technology. It is ideal for low power and

– V (Opr) = 2.0V to 3.6V

high speed 3.3V applications; it can be interfaced

to 5V signal environment for both inputs and

outputs.

■ Pin and function compatible with

74 series 162244

■ Latch-up performance exceeds 500mA

Any nG output control governs four bus buffers.

Output Enable input (nG) tied together gives full

16-bit operation.

(JESD 17)

■ ESD performance:

– HBM > 2000V

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

HIGH, the output are in high impedance state.

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

This device is designed to be used with 3 state

memory address drivers, etc.

The device circuits is including 26Ω series

resistance in the outputs. These resistors permit

to reduce line noise in high speed applications.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
