CHT-74132
CHT-74132 is Quad 2-Input NAND Schmitt Trigger manufactured by CISSOID.
Description
The CHT-74132 contains four independent 2-input NAND gates with Schmitt Trigger, performing the Boolean function :
Y AB
The gate switches at different points for positive and negative going signals. The difference between the positive voltage VT+ and the negative voltage VT- is defined as the hysteresis voltage VH
The CHT-74132 can operate with supply voltages from 3.3 to 5V (±10%).
Features
- Qualified from -55 to +225°C (Tj)
- 3.3 to 5V (±10%) supply voltages
- Latchup-free at any supply and tem- perature condition
- Validated at 225°C for 30000 hours
(CDIL14) and 20000 hours (CSOIC16) (and still on-going)
- Available in CDIL14 and CSOIC 16 hermetic standard package
Applications
- High temperature logic
- Noise immunity function
- Sensor interface
- Signal processing/conditioning
