74AHC377 74AHCT377 Octal D-type ip-op 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 specied in compliance with JEDEC standard No. 7-A. The 74AHC377 74AHCT377 has eight edge-triggered, D-type ip-ops with individual D inputs and Q outputs. A common clock input (CP) loads all ip-ops 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 ip-op. 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.
