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
