Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74VHCT541A
Octal Buffer/Line Driver with 3-STATE Outputs
Protection circuits ensure that 0V to 7V can be applied to
General Description
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.
The VHCT541A 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.
Note 1: Outputs in OFF-state.
The VHCT541A is an octal buffer/line driver designed to be
employed as memory and address drivers, clock drivers
and bus oriented transmitter/receivers.
Features
■ High Speed: tPD 5.5 ns (typ) at VCC 5V
This device is similar in function to the VHCT244A 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.
■ Low power dissipation: ICC
4 A (max) at TA 25 C
■ Power down protection is provided on all inputs and
outputs
■ Pin and function compatible with 74HCT541
