Octal D-type flip-flop with data enable; positive-edge trigger
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

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
