DESCRIPTION
The 74VHC541 is an advanced high-speed
CMOS OCTAL BUS BUFFER (3-STATE)
fabricated with sub-micron silicon gate and
double-layer metal wiring C
2
MOS technology.
The 3 STATE control gate operates as two input
AND suchthat if either G1 or G2 are high, all eight
outputs are in the high impedance state.
In order to enhance PC board layout, the
74VHC541 offers a pinout having inputs and
outputs on opposite sides of the package.
Power down protection is provided on all inputs
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.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
