CD54HCT377 (ACTIVE) High Speed CMOS Logic Octal D-Type Flip-Flops with Data Enable

High Speed CMOS Logic Octal D-Type Flip-Flops with Data Enable - CD54HCT377
Datasheet
 

Description

The ’HC377 and ’HCT377 are octal D-type flip-flops with a buffered clock (CP) common to all eight flip-flops. All the flip-flops are loaded simultaneously on the positive edge of the clock (CP) when the Data Enable (E\) is Low.
