HEF4093BT Quad 2-Input NAND Schmitt-Trigger
Data Sheet
General description:
The HEF4093B is a quad two-input NAND gate. Each input has a Schmitt trigger circuit. The gate switches at different points for positive-going and negative-going signals. The difference between the positive voltage (VT+) and the negative voltage (VT-) is defined as hysteresis voltage (VH).
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
It is also suitable for use over both the industrial (-40 oC to +85 oC) and automotive (-40 oC to +125 oC) temperature ranges
Features and benefits:
- Schmitt trigger input discrimination
- Fully static operation
- 5 V, 10 V, and 15 V parametric ratings
- Standardized symmetrical output characteristics
- Operates across the automotive temperature range from : -40 C to +125 C
- Complies with JEDEC standard JESD 13-B
Applications:
-
Wave and pulse shapers
-
Astable multivibrators
- Monostable multivibrators
