Overview
The TS3702IN is a micropower dual CMOS voltage comparator featuring push-pull outputs. It operates on a single supply of 2.7V to 16V or dual supplies of ±1.35V to ±8V. Typical supply current is 9µA per comparator, with input bias and offset currents at 1pA. Response time is typically 2µs for a 5mV overdrive. The device supports an operating temperature range of -40°C to +125°C and is housed in a DIP-8 package.
Feature Summary
- Push-pull CMOS output stage eliminates the need for external pull-up resistors
- Extremely low supply current consumption of 9µA typical per comparator
- High input impedance of 10^12 ohms typical with input common-mode voltage including ground
- Pin-to-pin and functionally compatible with bipolar LM393
Applications
- General purpose signal conditioning circuits
- Battery-powered systems requiring low power consumption
- Threshold detection applications
- Replacement for open-collector comparators in space-constrained designs
Procurement Notes
Verify the specific suffix 'IN' corresponds to the industrial temperature grade (-40°C to +125°C) and DIP-8 packaging configuration. Confirm that the required performance parameters align with the electrical characteristics specified in the official datasheet for this exact part number before finalizing procurement decisions.
Selection Notes
Select the TS3702IN when a dual comparator with push-pull outputs is required to save board space by removing external pull-up resistors. It is suitable for applications needing low power consumption and high input impedance. Ensure the operating environment falls within the specified industrial temperature range and voltage limits defined in the datasheet.
Part Context
The TS3702 series consists of micropower dual CMOS voltage comparators designed as improvements over standard bipolar comparators. The TS3702IN specifically denotes the industrial temperature variant packaged in a plastic DIP-8 format. This component belongs to STMicroelectronics' lineup of analog comparators offering high input impedance and fast response times.
Replacement Considerations
The TS3702 is pin-to-pin and functionally compatible with the bipolar LM393. Designers replacing LM393 devices should verify that the push-pull output characteristics of the TS3702 meet the circuit requirements without additional pull-up components.
FAQ
Does the TS3702 require external pull-up resistors?
No, the TS3702 features 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 up to VCC+ minus 1.2V or 1.5V depending on the specific conditions.
