HCT109

The 'HCT109 is dual J-K flip-flops with set and reset. It changes state with the positive transition of Clock (1CP and 2CP) and 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.

Features of the 'HCT109 are:(1)Asynchronous Set and Reset;(2)Schmitt Trigger Clock Inputs;(3)Typical f_MAX = 54MHz at V_CC = 5V, C_L = 15pF, T_A = 25oC;(4)Fanout (Over Temperature Range):Standard Outputs is 10 LSTTL Loads and Bus Driver Outputs is 15 LSTTL Loads;(5)Wide Operating Temperature Range:-55oC to 125oC;(6)Balanced Propagation Delay and Transition Times;(7)Significant Power Reduction Compared to LSTTL Logic ICs;(8)Operation:4.5V to 5.5V;(9)Direct LSTTL Input Logic Compatibility, V_IL= 0.8V (Max), V_IH = 2V (Min);(10)CMOS Input Compatibility, Il1A at V_OL, V_OH.

The absolute maximum ratings of the 'HCT109 can be summarized as:(1)DC Supply Voltage, V_CC:-0.5V to 7V;(2)DC Input Diode Current, I_IK:For V_I < -0.5V or V_I > V_CC + 0.5V is ±20mA;(3)DC Drain Current, per Output,I_O:For -0.5V < V_O < V_CC + 0.5V is ±25mA;(4)DC Output Diode Current,I_OK:For V_O < -0.5V or V_O > V_CC + 0.5V is ±20mA;(5)DC Output Source or Sink Current per Output Pin, I_O:For V_O > -0.5V or V_O < V_CC + 0.5V is ±25mA;(6)DC V_CC or Ground Current, I_CC:±50mA.
