Features
Description
• Asynchronous Set and Reset
• Schmitt Trigger Clock Inputs
• _TTAyp=ic2a5l_ofC_MAX = 54MHz at V_CC = 5V, C_L = 15pF,
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55^oC to 125^oC
The ’HC109 and ’HCT109 are dual J-K flip-flops with set and
reset. The flip-flop changes state with the positive transition
of Clock (1CP and 2CP).
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: N_IL = 30%, N_IH = 30% of V_CC
at V_CC = 5V
• HCT Types
- 4.5V to 5.5V Operation
- Direct LSTTL Input Logic Compatibility,
V_IL= 0.8V (Max), V_IH = 2V (Min)
- CMOS Input Compatibility, I_l ≤ 1µA at V_OL, V_OH
