TLC3702IDG4

Comparators Overview

The TLC3702IDG4 is a dual micropower voltage comparator utilizing Texas Instruments' LinCMOS process. It operates on a single supply from 3 V to 16 V, with an input offset voltage of 5 mV maximum at 25°C and 7 mV across the -40°C to 85°C industrial temperature range. The device features push-pull CMOS outputs capable of sourcing or sinking ±8 mA without external pullup resistors. Typical propagation delay is 2.7 μs with 5-mV overdrive, and typical supply current is 40 μA for both comparators.

Comparators Feature Summary

• Push-pull CMOS output stage drives capacitive loads directly without requiring power-consuming pullup resistors.
• LinCMOS process provides extremely stable input offset voltages with large differential input voltages.
• On-chip ESD protection circuitry withstands multiple high-voltage pulses while minimizing leakage currents.

Comparators Applications

• Interfaces compatible with modern HCMOS logic systems
• Single-supply analog signal conditioning
• Battery-powered applications requiring low power consumption

Comparators Procurement Notes

Verify that the ordering suffix 'DG4' corresponds to the specified lead-free and RoHS-compliant status as defined by Texas Instruments standards. Confirm the package designation matches the small outline requirements for your PCB layout. Ensure the industrial temperature grade (-40°C to 85°C) aligns with your system's environmental operating conditions before finalizing procurement.

Comparators Selection Notes

Select this component when low power consumption is critical alongside standard response times comparable to older bipolar comparators but with significantly lower quiescent current. The push-pull output eliminates the need for external pullup components, reducing board space and cost. Choose the industrial temperature variant if operation extends beyond commercial limits into colder environments.

Comparators Part Context

This device belongs to the TLC3702 family of dual micropower voltage comparators. It is functionally similar to the LM339 but utilizes one-twentieth of the power for similar response times. The LinCMOS process distinguishes it from standard CMOS devices by offering superior analog performance, including high input impedance and low bias currents, while maintaining digital compatibility.
