74ALVCH162374
Low Voltage 16-Bit D-Type Flip-Flop with Bushold
and 26Series Resistors in Outputs
General Description
The ALVCH162374 contains sixteen non-inverting D-type
flip-flops with 3-STATE outputs and is intended for bus ori-
ented applications. The device is byte controlled. A buff-
ered clock (CP) and output enable (OE) are common to
each byte and can be shorted together for full 16-bit opera-
tion.
The ALVCH162374 data inputs include active bushold cir-
cuitry, eliminating the need for external pull-up resistors to
hold unused or floating data inputs at a valid logic level.
The 74ALVCH162374 is also designed with 26series
resistors in the outputs. This design reduces line noise in
applications such as memory address drivers, clock drivers
and bus transceivers/transmitters.
The 74ALVCH162374 is designed for low voltage
(1.65V to 3.6V) VCC applications with output compatibility
up to 3.6V.
The 74ALVCH162374 is fabricated with an advanced
CMOS technology to achieve high speed operation while
maintaining low CMOS power dissipation.

Functional Description
The 74ALVCH162374 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
Logic Diagram
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 (CPn) transition. With the Output
Enable (OEn) LOW, the contents of the flip-flops are avail-
able at the outputs. When OEn is HIGH, the outputs go to
the high impedance state. Operations of the OEn input
does not affect the state of the flip-flops.
Byte 1 (0:7)
Byte 2 (8:15)

the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the Absolute Maximum Rat-
