1. General description
The HEF4093B is a quad 2-input NAND gate with Schmitt-trigger inputs. Inputs include clamp
diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of
VDD. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free
output signals.
2. Features and benefits
• Schmitt trigger input discrimination
• Fully static operation
• 5 V, 10 V, and 15 V parametric ratings
• Wide supply voltage range from 3.0 V to 15.0 V
• CMOS low power dissipation
• High noise immunity
• Standardized symmetrical output characteristics
• Complies with JEDEC standard JESD 13-B
• ESD protection:
• HBM JESD22-A114F exceeds 2000 V
• MM JESD22-A115-B exceeds 200 V
• Specified from -40 °C to +85 °C and -40 °C to +125 °C
3. Applications
• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators
