74VHCT540A
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The VHCT540A is an advanced high-speed CMOS device
fabricated with silicon gate CMOS technology. It achieves
the high-speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation.
The VHCT540A is an octal buffer/line driver designed to be
employed as memory and address drivers, clock drivers
and bus oriented transmitter/receivers.
This device is similar in function to the VHCT240A while
providing flow-through architecture (inputs on opposite side
from outputs). This pinout arrangement makes this device
especially useful as an output port for microprocessors,
allowing ease of layout and greater PC board density.
Protection circuits ensure that 0V to 7V can be applied to
the input and output (Note 1) pins without regard to the
supply voltage. This device can be used to interface 3V to
5V systems and two supply systems such as battery
backup. This circuit prevents device destruction due to mis-
matched supply and input voltages.
