The TC74VHC540/TC74VHC541 are advanced high speed
CMOS OCTAL BUS BUFFERs fabricated with silicon gate
C
2
MOS technology.
They achieve the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The TC74VHC540 is an inverting type, and the TC74VHC541
is a non-inverting type.
When either
1
G
or
2
G
are high, the terminal outputs are in
the high-impedance state.
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 V to 3 V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
