Dual J-K Flip-Flop with Set and Reset
Negative-Edge Trigger
March 1998
Features
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
• Hysteresis on Clock Inputs for Improved Noise
Immunity and Increased Input Rise and Fall Times
• Asynchronous Set and Reset
Description
• Complementary Outputs
The Harris CD74HC112 and CD74HCT112 utilize silicongate CMOS technology to achieve operating speeds
equivalent to LSTTL parts. They exhibit the low power
consumption of standard CMOS integrated circuits, together
with the ability to drive 10 LSTTL loads.
• Buffered Inputs
• Typical fMAX = 60MHz at VCC = 5V, CL = 15pF,
TA = 25oC
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
These flip-flops have independent J, K, Set, Reset, and
Clock inputs and Q and Q outputs. They change state on the
negative-going transition of the clock pulse. Set and Reset
are accomplished asynchronously by low-level inputs.
• Wide Operating Temperature Range . . . -55oC to 125oC
The 74HCT logic family is functionally as well as pincompatible with the standard 74LS logic family.
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL
Logic ICs
.
Ordering Information
• HC Types
- 2V to 6V Operation
- High Noise Immunity: NIL = 30%, NIH = 30% of VCC
