TLC374MJ

Comparators Overview

The TLC374MJ is a quadruple differential comparator fabricated using LinCMOS technology, designed for operation from single or dual power supplies with voltages ranging from 2 V to 18 V. It features four independent comparators in a 14-pin ceramic dual in-line package (CDIP). The device operates over the full military temperature range of -55°C to 125°C. Key electrical characteristics include an input offset voltage of up to 5 mV at 25°C and a typical response time of 200 ns for TTL-level input steps. Supply current is typically 300 µA at 5 V.

Comparators Feature Summary

• Built-in electrostatic discharge protection circuits rated at 1000 V using human body model testing.
• Extremely high input impedance allowing direct interfacing with high-impedance sources.
• Outputs are n-channel open-drain configurations compatible with TTL, MOS, and CMOS logic families.
• Common-mode input voltage range includes ground potential.

Comparators Applications

• Precision threshold detection circuits
• Voltage monitoring systems
• Waveform generation applications

Comparators Procurement Notes

Verify that the component matches the specific military-grade temperature rating of -55°C to 125°C required for the application environment. Confirm the CDIP package type aligns with the printed circuit board footprint and mounting requirements. Ensure the supply voltage constraints between 2 V and 18 V are strictly observed during system design to prevent damage.

Comparators Selection Notes

Select this part when wide supply voltage flexibility and low input bias current are critical. The military temperature range makes it suitable for harsh environments where standard commercial grades fail. Consider the open-drain output requirement for wired-AND logic implementation. Verify that the 200 ns response time meets the speed requirements of the target signal processing chain.

Comparators Part Context

This component belongs to the TLC374 family of LinCMOS quadruple differential comparators manufactured by Texas Instruments. The 'M' suffix specifically denotes the military temperature grade (-55°C to 125°C), distinguishing it from commercial (C) and industrial (I) variants. The 'J' suffix indicates the ceramic dual in-line package construction.

Comparators Replacement Considerations

TLC374MJB is a pin-compatible alternative within the same manufacturer's lineup offering identical specifications and packaging options.
