1 / 6 page 74ACT11379 QUAD DTYPE FLIPFLOP WITH CLOCK ENABLE SCAS103 − JANUARY 1990 − REVISED APRIL 1993 Copyright 1993, Texas Instruments Incorporated 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 • Inputs Are TTL-Voltage Compatible • Contains Four Flip-Flops with Double-Rail Outputs • Clock Enable Latched to Avoid False Clocking • Applications Include: Buffer/Storage Registers, Shift Registers, Pattern Generators • Flow-Through Architecture to Optimize PCB Layout • Center-Pin V CC and GND Configurations to Minimize High-Speed Switching Noise • EPICt (Enhanced-Performance Implanted CMOS) 1- mm Process • 500-mA Typical Latch-Up Immunity at 125 °C • Package Options Include Plastic Small Outline Packages, and Standard Plastic 300-mil DIPs description These circuits are positive-edge-triggered D-type flip-flops with a clock-enable input. Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse if CLKEN is low. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of 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 CLKEN input. The 74ACT11379 is characterized for operation from − 40 °C to 85°C.
