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

74LVT16374 • 74LVTH16374
Low Voltage 16-Bit D-Type Flip-Flop
with 3-STATE Outputs
General Description
Features
The LVT16374 and LVTH16374 contain sixteen non-inverting 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 common 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.
■ Input and output interface capability to systems at
5V VCC
These flip-flops are designed for low-voltage (3.3V) VCC
applications, but with the capability to provide a TTL interface 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.
■ Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH16374),
also available without bushold feature (74LVT16374)
■ Live insertion/extraction permitted
■ Power Up/Power Down high impedance provides
glitch-free bus loading
■ Outputs source/sink 32 mA/64 mA
■ Functionally compatible with the 74 series 16374
■ Latch-up performance exceeds 500 mA
■ ESD performance:
Human-body model ! 2000V
Machine model ! 200V
Charged-device model ! 1000V
■ Also packaged in plastic Fine-Pitch Ball Grid Array

Functional Description
Each flip-flop will store the state of their individual D-type
inputs that meet the setup and hold time requirements on
the LOW-to-HIGH Clock (CPn) transition. With the Output
Enable (OEn) LOW, the contents of the flip-flops are available at the outputs. When OEn is HIGH, the outputs go to
the high impedance state. Operation of the OEn input does
not affect the state of the flip-flops.
The LVT16374 and LVTH16374 consist of sixteen
edge-triggered flip-flops with individual D-type inputs and
3-STATE true outputs. The device is byte controlled with
each byte functioning identically, but independent of the
other. The control pins can be shorted together to obtain
full 16-bit operation. Each byte has a buffered clock and
buffered Output Enable common to all flip-flops within that
byte. The description which follows applies to each byte.
