DESCRIPTION
The 74ACT16541 is an advanced high-speed
CMOS
fabricated with sub-micron silicon gate and
double-layer metal wiring C
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 interface directly High
Speed CMOS systems with TTL and NMOS
components.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
