74LV574 Octal D-type flip-flop; positive edge-trigger; 3-state Rev. 04 -- 14 May 2009 Product data sheet 1. General description The 74LV574 is an octal D-type flip-flop featuring separate D-type inputs for each flip-flop and non-inverting 3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops. It is a low-voltage Si-gate CMOS device and is pin and functionally compatible with the 74HC574 and 74HCT574. The eight 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 eight flip-flops is 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. 2. Features n n n n n n n n n Wide operating voltage: 1.0 V to 5.5 V Optimized for low voltage applications: 1.0 V to 3.6 V Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V Typical output ground bounce < 0.8 V at VCC = 3.3 V and Tamb = 25 C Typical HIGH-level output voltage (VOH) undershoot: > 2 V at VCC = 3.3 V and Tamb = 25 C ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V Common 3-state output enable input Multiple package options Specified from -40 C to +85 C and from -40 C to +125 C 3.
