U74AHC377

DESCRIPTION 

The U74AHC377 is a high-speed Si-gate CMOS device and 

is compatible with low-power Schottky TTL (LSTTL). 

The U74AHC377 has eight edge-triggered, D-type flip-flops 

with individual D inputs and Q outputs. A common clock input 

(CLK) loads all flip-flops simultaneously when the data enable 

input (EN ) 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 EN input is only 

required to be stable one set-up time prior to the LOW-to-HIGH 

transition for predictable operation. 

 FEATURES 

* Balanced propagation delays 

* All inputs have Schmitt-trigger actions 

* Inputs accept voltages higher than Vcc

* Ideal for addressable register applications 

* Data enable for address and data synchronization 

* Eight positive-edge triggered D-type flip-flops
