74AHC377; 74AHCT377 Octal D-type flip-flop with data enable; positive-edge trigger Rev. 02 — 12 June 2008 Product data sheet 1. General description The 74AHC377; 74AHCT377 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7-A. The 74AHC377; 74AHCT377 has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. A common clock input (CP) loads all flip-flops simultaneously when the data enable input (E) is LOW. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding output (Qn) of the flip-flop. The E input is only required to be stable one set-up time prior to the LOW-to-HIGH transition for predictable operation. For versions associated with the 74AHC377; 74AHCT377, refer to the following: • For the master reset version, see 74AHC273; 74AHCT273 • For the transparent latch version, see 74AHC373; 74AHCT373 • For the 3-state version, see 74AHC374; 74AHCT374 2.
