74ALVC16374 Low Voltage 16-Bit D-Type Flip-Flop with 3.6V Tolerant Inputs and Outputs
74ALVC16374
Low Voltage 16-Bit D-Type Flip-Flop
with 3.6V Tolerant Inputs and Outputs
General Description
The ALVC16374 contains 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 74ALVC16374 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74ALVC16374 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

74ALVC16374
Functional Description
The 74ALVC16374 consists of sixteen edge-triggered
flip-flops with individual D-type inputs and 3-STATE true
outputs. The device is byte controlled with each byte func-
tioning identically, but independent of the other. The control
pins can be shorted together to obtain full 16-bit operation.
Each clock has a buffered clock and buffered Output
Enable common to all flip-flops within that byte. The
description which follows applies to each byte. Each
flip-flop will store the state of their individual I inputs that
meet the setup and hold time requirements on the
LOW-to-HIGH Clock (CP
n
) transition. With the Output
Enable (OE
n
) LOW, the contents of the flip-flops are avail-
able at the outputs. When OE
n
is HIGH, the outputs go to
the high impedance state. Operations of the OE
n
input
does not affect the state of the flip-flops.
