DESCRIPTION
The 74LCX16541 is an advanced high-speed
CMOS 16-BIT BUS BUFFER (3-STATE) fabricat-
ed with sub-micron silicon gate and double-layer
metal wiring C2MOS tecnology.
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 driveres, etc.
It hase same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power con-
sumption.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.
