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
