Description
The 74LCX162541 is a low voltage CMOS 16 bit
bus buffer (non-inverted) fabricated with sub-
micron silicon gate and double-layer metal wiring
C2MOS 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.
This is composed of two 8-bit sections with
separate output-enable signals. For either 8-bit
buffers section, the 3 state control gate operates
as a two input AND such that if either nG1 and
nG2 are high, all outputs are in the high
impedence state.
This device is designed to be used with 3 state
memory address drivers, etc.
The device circuits is including 26
Ω 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.
