TS3704CD

Overview

The TS3704CD is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics. It operates on a single supply of 2.7V to 16V or dual supplies of ±1.35V to ±8V. The device features a push-pull CMOS output stage, eliminating the need for external pull-up resistors. Key electrical parameters include a typical supply current of 9µA per comparator, an input offset voltage of 5mV, and a response time of 1.2µs (low-to-high) and 2µs (high-to-low). It is housed in a SO14 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 10^12Ω and input common-mode voltage range includes ground.
• Pin-to-pin and functionally compatible with bipolar LM339.

Applications

• General purpose analog signal comparison
• Voltage monitoring circuits
• Threshold detection systems

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The 'CD' designation indicates the SO14 plastic package. Confirm that the industrial temperature range (0°C to +70°C) meets your system requirements. Ensure compatibility with your PCB footprint for the SO14 form factor before finalizing procurement.

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 5mV input offset voltage and 1.2µs response time are sufficient for your application's precision and speed requirements.

Part Context

The TS3704CD belongs to the TS3704 family of micropower quad CMOS voltage comparators. This series is designed as a low-power alternative to traditional bipolar comparators like the LM339. The 'C' suffix denotes the industrial temperature range, while 'D' specifies the SO14 surface-mount package.

Replacement Considerations

The datasheet confirms pin-to-pin and functional compatibility with the bipolar LM339. Designers replacing LM339 units should verify that the CMOS input characteristics and push-pull outputs align with their existing circuit topology.
