TS3704ID

Overview

The TS3704ID is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics, housed in a 14-SOIC surface-mount package. It operates within a single supply range of 2.7V to 16V or dual supplies of ±1.35V to ±8V. The device features an industrial temperature range of -40°C to +125°C and includes four independent comparators with push-pull CMOS outputs. Key electrical specifications include a maximum input offset voltage of 5mV at 10V, typical supply current of 9µA per comparator, and response times as low as 0.7µs for low-to-high transitions under specific overdrive conditions.

Feature Summary

• Push-pull CMOS output stage eliminates the need for external pull-up resistors typically required by open-collector comparators.
• Extremely low power consumption with typical supply current of 9µA per comparator, significantly lower than bipolar equivalents.
• High input impedance of 10^12Ω and input common-mode voltage range that includes ground potential.
• Pin-to-pin and functionally compatible with standard bipolar LM339 devices.

Applications

• Battery-operated equipment requiring low power consumption
• Signal conditioning circuits utilizing window comparator configurations
• General-purpose analog signal comparison tasks

Procurement Notes

Verify the specific suffix 'ID' corresponds to the SO14 package and Industrial temperature grade (-40°C to +125°C) when ordering. Confirm packaging options such as tape and reel availability if high-volume production is intended. Ensure design compliance with absolute maximum ratings, particularly regarding differential input voltage limits and power dissipation constraints for the SO14 package.

Selection Notes

Select this component for applications demanding low quiescent current and direct drive capabilities without external pull-up components. The wide supply voltage range supports both single and dual rail systems. Consider the 5mV maximum input offset voltage for precision requirements. Verify thermal management needs based on the specified power dissipation limits for the SO14 package under expected operating conditions.

Part Context

The TS3704 series comprises micropower quad CMOS voltage comparators designed as low-power alternatives to traditional bipolar comparators. The TS3704ID specifically denotes the industrial temperature variant packaged in a 14-pin Small Outline Integrated Circuit (SO14). This family maintains functional compatibility with industry-standard parts while offering reduced power consumption and integrated push-pull outputs.

Replacement Considerations

The TS3704ID is functionally compatible with the bipolar LM339. Designers replacing LM339 units should verify that the target application does not require open-collector outputs, as the TS3704 utilizes push-pull stages.
