DESCRIPTION
The 74LCX162244 is a low voltage CMOS 16 BIT
BUS BUFFER (NON-INVERTED) fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low power
and high speed 3.3V applications; it can be
interfaced to 5V signal environment for both inputs
and outputs.
Any nG output control governs four BUS BUFF-
ERS. Output Enable input (nG) tied together gives
full 16-bit operation.
When nG is LOW, the outputs are on. When nG is
HIGH, the output are in high impedance state.
This device is designed to be used with 3 state
memory address drivers, etc.
The device circuits is including 26Ω series resis-
tance in the outputs. These resistors permit to re-
duce line noise in high speed applications.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.
