Overview
The TS3704CN is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics. It features an extremely low supply current of 9µA typ per comparator and operates on a wide single supply range from 2.7V to 16V or dual supplies (±1.35V to ±8V). The device includes push-pull CMOS outputs, eliminating the need for external pull-up resistors. Electrical characteristics include an input offset voltage of up to 6.5mV, input bias current of 600pA max, and response times of 1.2µs (low-to-high) and 2µs (high-to-low) with 5mV overdrive. It is housed in a DIP14 package.
Feature Summary
- Push-pull CMOS output stage eliminates the requirement for external pull-up resistors.
- Extremely low power consumption with typical supply current of 9µA per comparator.
- High input impedance of 10^12 Ω typical with common-mode voltage range including ground.
- Pin-to-pin and functionally compatible with bipolar LM339 devices.
Applications
- Battery-powered systems requiring low quiescent current
- Threshold detection circuits
- Voltage monitoring applications
Procurement Notes
Verify that the specific part number matches the required temperature grade and packaging format. Confirm the DIP14 plastic package type aligns with board layout constraints. Ensure compliance with RoHS standards as indicated by ECOPACK specifications. Review absolute maximum ratings regarding supply voltage and differential input limits before integration.
Selection Notes
Select this component when low power consumption is critical compared to standard bipolar comparators. The push-pull output simplifies circuit design by removing external components. Verify that the operating temperature range meets system requirements, as industrial grades offer wider ranges than commercial options.
Part Context
The TS3704 series consists of micropower quad CMOS voltage comparators designed for battery-operated applications. The CN suffix denotes the commercial temperature range (0°C to +70°C) and the DIP14 through-hole package. This variant provides a cost-effective solution for general-purpose comparison tasks where space and power efficiency are priorities.
Replacement Considerations
LM339DTBR2G is listed as a substitute part number.
FAQ
Does the TS3704CN require external pull-up resistors?
No, the TS3704CN utilizes a push-pull CMOS output stage, which 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 from 0V to VCC+ minus a small margin depending on the specific supply voltage.
