Description
Description
The UTC339 consists of four independent voltage comparators designed specifically to operate from a single power supply over a wide voltage range.
Features
- Single or dual supply operation
- Wide operating supply range(Vcc=2V~36V)
- Input common-mode voltage includes ground
- Low supply current drain ICC=0.8mA(Typical)
- Open collector outputs for wired and connection
- Low input bias current Ibias=25nA(Typical)
- Low output saturation voltage
- Output compatible with TTL ,DTL, and CMOS logic system
