Overview
The TS372CD is a low-power dual CMOS voltage comparator manufactured by STMicroelectronics. It operates within a single supply range of 3 V to 16 V or dual supplies of ±1.5 V to ±8 V. The device features an extremely low input bias current of 1 pA typical and a very low supply current of 0.1 mA per comparator. It provides a fast response time of 200 ns for TTL level input steps and includes an output compatible with TTL, MOS, and CMOS logic families. The component is housed in an SO-8 plastic micropackage and supports an operating temperature range from 0°C to +70°C.
Feature Summary
- Extremely low input bias current and offset currents
- Very low supply current independent of supply voltage
- Fast response time for TTL level input steps
- Output compatible with TTL, MOS, and CMOS
Applications
- Battery powered electronics
- General-purpose portable devices
- General-purpose low voltage applications
Procurement Notes
Verify the specific ordering suffix to confirm the package type and packing method. The 'CD' designation indicates an SO-8 tube configuration. Confirm that the industrial temperature range meets the operational requirements of the target environment. Ensure compatibility with existing PCB footprints designed for the SO-8 package dimensions.
Selection Notes
Select this component when low power consumption is critical alongside high input impedance. The wide supply voltage range allows flexibility in system design without requiring additional regulation. Consider the open-drain output characteristics when designing pull-up resistor networks for interfacing with different logic families.
Part Context
This part belongs to the TS372 series of precision voltage comparators. The series utilizes silicon gate MOS technology to achieve an excellent consumption-speed ratio. Other variants in the family include versions with extended temperature ranges and different packaging options such as DIP-8.
Replacement Considerations
TS372IDT: Extended temperature range (-40°C to +125°C) in tape and reel packaging.
