74HC574N

74HC574; 74HCT574 Octal D-type flip-flop; positive edge-trigger; 3-state Rev. 6 26 January 2015 Product data sheet 1. General description The 74HC574; 74HCT574 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A. The 74HC574; 74HCT574 are octal D-type flip-flops featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops. The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition. When OE is LOW the contents of the 8 flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. The 74HC574; 74HCT574 is functionally identical to: 74HC564: but has non-inverting outputs 74HC374; 74HCT374: but has a different pin arrangement 2. Features and benefits 3-state non-inverting outputs for bus oriented applications 8-bit positive, edge-triggered register Common 3-state output enable input ESD protection: HBM JESD22-A114F exceeds 2 000 V MM JESD22-A115-A exceeds 200 V Specified from 40 Cto+85 C and from 40 Cto+125 C 3.
