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.

General Description
The LVT374 and LVTH374 are high-speed, low-power
octal D-type flip-flops featuring separate D-type inputs
for each flip-flop and 3-STATE outputs for bus-oriented
applications. A buffered Clock (CP) and Output Enable
(OE) are common to all flip-flops.
The LVTH374 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These octal flip-flops are designed for low-voltage (3.3V)
V
CC
applications, but with the capability to provide a TTL
interface to a 5V environment. The LVT374 and
LVTH374 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
