1 / 9 page © 2005 Fairchild Semiconductor Corporation DS009961 www.fairchildsemi.com November 1988 Revised March 2005 74AC377 • 74ACT377 Octal D-Type Flip-Flop with Clock Enable General Description The AC/ACT377 has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common buff- ered Clock (CP) input loads all flip-flops simultaneously, when the Clock Enable (CE) is LOW. The register is fully edge-triggered. The state of each D input, one setup time before the LOW-to-HIGH clock transi- tion, is transferred to the corresponding flip-flop’s Q output. The CE input must be stable only one setup time prior to the LOW-to-HIGH clock transition for predictable operation. Features s ICC reduced by 50% s Ideal for addressable register applications s Clock enable for address and data synchronization applications s Eight edge-triggered D-type flip-flops s Buffered common clock s Outputs source/sink 24 mA s See 273 for master reset version s See 373 for transparent latch version s See 374 for 3-STATE version s ACT377 has TTL-compatible inputs Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Pb-Free package per JEDEC J-STD-020B. Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B).
