INTEGRATED CIRCUITS 74LVC574A Octal D-type flip-flop with 5-volt tolerant inputs/outputs; positive edge-trigger (3-State) Product specification 1998 Jul 29 Philips Semiconductors Philips Semiconductors Product specification Octal D-type flip-flop with 5-volt tolerant 74LVC574A inputs/outputs; positive edge-trigger (3-State) Inputs can be driven from either 3.3V or 5V devices. In 3-State FEATURES operation, outputs can handle 5V. This feature allows the use of • 5-volt tolerant inputs/outputs, for interfacing with 5-volt logic these devices as translators in a mixed 3.3V/5V environment. • Supply voltage range of 2.7V to 3.6V The 74LVC574A is an octal D-type flip-flop featuring separate • Complies with JEDEC standard no. 8-1A D-type inputs for each flip-flop and 3-State
