74VHCT540A
Octal Buffer/Line Driver with 3-STATE Outputs
Features
■ High Speed: tPD = 5.4ns (Typ.) at VCC = 5V
■ Low Power Dissipation: ICC = 4A (Max.) at TA = 25°C
■ Power down protection is provided on all inputs and
outputs
■ Pin and function compatible with 74HCT540
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 dissipation.
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 micro-
processors, allowing ease of layout and greater PC
board density.
Protection circuits ensure that 0V to 7V can be applied to
the input and output(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
mismatched supply and input voltages.
Note:
1. Outputs in OFF-State.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number. Pb-Free package per JEDEC J-STD-020B.
