1 / 5 page SN74F377A OCTAL D-TYPE FLIP-FLOP WITH CLOCK ENABLE SDFS018D – D2932, MARCH 1987 – REVISED OCTOBER 1993 Copyright © 1993, Texas Instruments Incorporated 2–1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 • Contains Eight D-Type Flip-Flops With Single-Rail Outputs • Clock Enable Latched to Avoid False Clocking • Applications Include: Buffer/Storage Registers Shift Registers Pattern Generators • Buffered Common Enable Input • Package Options Include Plastic Small-Outline Packages and Standard Plastic 300-mil DIPs description The SN74F377A is a monolithic, positive-edge-triggered, octal, D-type flip-flop with clock enable inputs. The SN74F377A features a latched clock enable (CE) input. Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse if CE is low. Clock triggering occurs at a particular voltage level and is not directly related to the positive-going pulse. When the clock input is at either the high or low level, the D input signal has no effect at the output. The circuits are designed to prevent false clocking by transitions at the CE input. The SN74F377A is characterized for operation from 0 °C to 70°C.
