1 / 5 page 54ACT11109, 74ACT11109 DUAL J-K POSITIVE-EDGE-TRIGGERED FLIP-FLOPS WITH CLEAR AND PRESET SCAS451 – FEBRUARY 1987 – REVISED APRIL 1993 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 Copyright © 1993, Texas Instruments Incorporated 2–1 • Inputs Are TTL-Voltage Compatible • Flow-Through Architecture Optimizes PCB Layout • Center-Pin V CC and GND Configurations Minimize High-Speed Switching Noise • EPIC™ (Enhanced-Performance Implanted CMOS) 1- µm Process • 500-mA Typical Latch-Up Immunity at 125 °C • Package Options Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs description These devices contain two independent J-K positive-edge-triggered flip-flops. A low level at the preset (1PRE or 2PRE) or clear (1CLR or 2CLR) input sets or resets the outputs regardless of the levels of the other inputs. When PRE and CLR are inactive (high), data at the J and K inputs meeting the setup time requirements are transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval, data at the J and K inputs may be changed without affecting the levels at the outputs. These versatile flip-flops can perform as toggle flip-flops by grounding K and tying J high. They also can perform as D-type flip-flops if J and K are tied together. The 54ACT11109 is characterized for operation over the full military temperature range of – 55 °C to 125°C. The 74ACT11109 is characterized for operation from – 40 °C to 85°C.
