1. General description

The HEF4013B is a dual D-type flip-flop with set and reset; positive-edge trigger. Inputs include

clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in

excess of VDD. Schmitt-trigger action on the clock input makes the circuit highly tolerant of slower

clock rise and fall times.

2. Features and benefits

• Wide supply voltage range from 3.0 V to 15.0 V

• CMOS low power dissipation

• High noise immunity

• Tolerant of slow clock rise and fall times

• Fully static operation

• 5 V, 10 V, and 15 V parametric ratings

• Standardized symmetrical output characteristics

• Specified from -40 °C to +125 °C

• Complies with JEDEC standard JESD 13-B

• ESD protection:

• HBM JESD22-A114F exceeds 2000 V

• MM JESD22-A115-B exceeds 200 V

3. Applications

• Counters and dividers

• Registers

• Toggle flip-flops
