The TC74VHCT540A and 541A 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 TC74VHCT540A is an inverting type and, the
TC74VHCT541A is a non-inverting type.
When either
1
G
or
2
G
are high, the terminal outputs are in
the high-impedance state.
The input voltage are compatible with TTL output voltage.
These devices may be used as a level converter for interfacing
3.3 V to 5 V system.
Input protection and output circuit ensure that 0 to 5.5 V can
be applied to the input and output (Note) pins without regard to
the supply voltage. These structure prevents device destruction
due to mismatched supply and input/output voltages such as
battery back up, hot board insertion, etc.
