They are specified in compliance with JEDEC applications standard no. 7A. Eight positive-edge triggered D-type flip-flops The 74HC/HCT377 have eight edge-triggered, D-type See 273 for master reset version flip-flops with individual D inputs and Q outputs. A common See 373 for transparent latch version clock (CP) input loads all flip-flops simultaneously when See 374 for 3-state version the data enable (E) is LOW. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is Output capability: standard transferred to the corresponding output (Q ) of the flip-flop. n I category: MSI CC The E input must be stable only one set-up time prior to the LOW-to-HIGH transition for predictable operation.
