74ALVCH16374
Rev. 6.1 — 7 March 2019
2.5 V/3.3 V 16-bit edge-triggered D-type flip-flop; 3-state
Product data sheet
1. General description
The 74ALVCH16374 is 16-bit edge-triggered flip-flop featuring separate D-type inputs for each
flip-flop and 3-state outputs for bus oriented applications.
Incorporates bus hold data inputs which eliminate the need for external pull-up or pull-down
resistors to hold unused inputs.
The 74ALVCH16374 consists of 2 sections of eight edge-triggered flip-flops. A clock (CP) input and
an output enable (OE) are provided per 8-bit section.
The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time
requirements on the LOW-to-HIGH CP transition.
When OE is LOW, the contents of the flip-flops are available at the outputs. When OE is HIGH, the
outputs go the high-impedance OFF-state. Operation of the OE input does not affect the state of
the flip-flops.
