74HC377 74HCT377 Octal D-type flip-flop with data enable positive-edge trigger Rev. 3 25 September 2013 Product data sheet 1. General description The 74HC377 74HCT377 is an octal positive-edge triggered D-type flip-flop. The device features clock (CP) and data enable (E) inputs. When E is LOW, the outputs Qn assume the state of their corresponding Dn inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. Input E must be stable one set-up time prior to the LOW-to-HIGH transition for predictable operation. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of V . CC 2. Features and benefits Common clock and master reset Eight positive edge-triggered D-type flip-flops Complies with JEDEC standard no. 7A Input levels: For 74HC377: CMOS level For 74HCT377: TTL level ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V.
