Overview
The TS3704IN is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics. It features four independent comparators in a 14-DIP package with an operating temperature range of -40°C to +125°C. The device operates on a single supply from 2.7V to 16V or dual supplies of ±1.35V to ±8V. Key electrical parameters include a typical supply current of 9µA per comparator, input bias and offset currents of 1pA typ., and a response time of 2µs typ. for a 5mV overdrive.
Feature Summary
- Push-pull CMOS output stage eliminates the need for external pull-up resistors.
- Extremely low power consumption with 9µA typical supply current per comparator.
- High input impedance of 10^12 Ω typical with input common-mode voltage including ground.
- Pin-to-pin and functionally compatible with bipolar LM339 devices.
Applications
- General-purpose analog signal conditioning
- Voltage monitoring circuits
- Threshold detection systems
Procurement Notes
Verify component authenticity through authorized channels as the TS3704IN may be discontinued. Confirm that the specific order code matches the required industrial temperature grade (-40°C to +125°C). Ensure compatibility with existing PCB footprints for the 14-DIP plastic package before finalizing procurement decisions.
Selection Notes
Select this component when low power consumption and high input impedance are critical requirements. The push-pull output simplifies circuit design by removing external components. Verify that the operating voltage range and temperature specifications align with the target application environment.
Part Context
The TS3704 belongs to the TS3704 family of micropower quad CMOS voltage comparators. It serves as a low-power alternative to traditional bipolar comparators like the LM339, offering similar performance characteristics while significantly reducing power consumption and eliminating the need for pull-up resistors.
Replacement Considerations
TLC3704IN (Texas Instruments) is listed as a similar replacement part number.
FAQ
Does the TS3704 require external pull-up resistors?
No, the TS3704 features a push-pull CMOS output stage that eliminates the need for external pull-up resistors typically required by open-collector output comparators.
What is the input common-mode voltage range?
The input common-mode voltage range includes ground (GND), extending up to VCC+ minus 1.2V to 1.5V depending on the specific conditions.
