The TC74VHC540 and 541 are advanced high speed CMOS
OCTAL BUS BUFFERs fabricated with silicon gate CMOS
technology.
They achieve the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The TC74VHCV540 is an inverting type, and the TC74VHCV541
is a non-inverting type.
When either G1 or G2 are high, the terminal outputs are in
the high-impedance state.
Input pin have hysteresis between the positive-going and
negative-going thresholds. Thus the TC74VHCV540 and 541 are
capable of squaring up transitions of slowly changing input
signals and provides an improved noise immunity.
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.
Note: Output in off-state
Features
