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

74LVT16374 • 74LVTH16374 Low Voltage 16-Bit D-Type Flip-Flop with 3-STATE Outputs
January 1999
Revised June 2005
74LVT16374 • 74LVTH16374
Low Voltage 16-Bit D-Type Flip-Flop
with 3-STATE Outputs
General Description
The LVT16374 and LVTH16374 contain sixteen non-invert-
ing D-type flip-flops with 3-STATE outputs and is intended
for bus oriented applications. The device is byte controlled.
A buffered clock (CP) and Output Enable (OE) are com-
mon to each byte and can be shorted together for full 16-bit
operation.
The LVTH16374 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These flip-flops are designed for low-voltage (3.3V) V
CC
applications, but with the capability to provide a TTL inter-
face to a 5V environment. The LVT16374 and LVTH16374
are fabricated with an advanced BiCMOS technology to
achieve high speed operation similar to 5V ABT while
maintaining a low power dissipation.
