FEATURES
DESCRIPTION
● Asynchronous Set and Reset● Schmitt Trigger Clock Inputs
● TTAyp=ic2a5lofCMAX = 54MHz at VCC = 5V, CL = 15pF,
● Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
● Wide Operating Temperature Range . . . -55oC to 125oC The flip-flop is set and reset by active-low S and R, respectively. A low on both the set and reset inputs simultaneously will force both Q and Q outputs high. However, both set and reset going high simultaneously results in an unpredictable output condition. Ordering Information
● Balanced Propagation Delay and Transition Times
● Significant Power Reduction Compared to LSTTL Logic ICs
● HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
● HCT Types - 4.5V to 5.5V Operation - Direct LSTTL Input Logic Compatibility, VIL= 0.8V (Max), VIH = 2V (Min) - CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH Pinout CD54HC109, CD54HCT109 (CERDIP) CD74HC109, CD74HCT109 (PDIP, SOIC) TOP VIEW PART NUMBER TEMP.
