DESCRIPTION
The 74VHCT541A is an advanced high-speed
CMOS OCTAL BUS BUFFER (3-STATE)
fabricated with sub-micron silicon gate and
double-layer metal wiring C2MOS technology.
The 3 STATE control gate operates as two input
AND such that if either G1 and G2 are high, all
eight outputs are in the high impedance state.

In order to enhance PC board layout, the
74VHCT541 offers a pinout having inputs and
outputs on opposite sides of the package.
Power down protection is provided on all inputs
and outputs and 0 to 7V can be accepted on
inputs with no regard to the supply voltage. This
device can be used to interface 5V to 3V since all
inputs are equipped with TTL threshold.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
