MC74VHCT541A
Octal Bus Buffer
The MC74VHCT541A is an advanced high speed CMOS octal bus
buffer fabricated with silicon gate CMOS technology. It achieves high
speed operation similar to equivalent Bipolar Schottky TTL while
maintaining CMOS low power dissipation.
The MC74VHCT541A is a noninverting, 3−state, buffer/line
driver/line receiver. When either OE1 or OE2 is high, the terminal
outputs are in the high impedance state.
The VHCT inputs are compatible with TTL levels. This device can
be used as a level converter for interfacing 3.3 V to 5.0 V, because it
has full 5.0 V CMOS level output swings.
The VHCT541A input and output (when disabled) structures
provide protection when voltages between 0 V and 5.5 V are applied,
regardless of the supply voltage. These input and output structures
help prevent device destruction caused by supply
voltage−input/output voltage mismatch, battery backup, hot insertion,
etc.
