74ALVCH16374 2.5 V/3.3 V 16-bit edge-triggered D-type flip-flop 3-state Rev. 6.1 7 March 2019 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. 2.
