TLC374MFKB

Comparators Overview

The TLC374MFKB is a quadruple differential comparator fabricated using LinCMOS technology, housed in a 20-pin ceramic chip carrier (FK) package. It operates within a supply voltage range of 4 V to 16 V and supports a full military temperature range from -55°C to 125°C. The device features four independent comparators with n-channel open-drain outputs compatible with TTL, MOS, and CMOS logic families. Key electrical characteristics include an input bias current of 5 pA typical at 25°C, an input offset voltage of 5 mV maximum at 25°C, and a response time of 200 ns typical for a TTL-level input step.

Comparators Feature Summary

• LinCMOS fabrication enables high input impedance and extremely low input bias current.
• Outputs are n-channel open-drain configurations allowing positive-logic wired-AND relationships.
• Internal electrostatic discharge protection circuits provide a 1000-V human body model rating.
• Common-mode input voltage range includes ground potential.

Comparators Applications

• High-impedance signal source interfacing
• Military-grade analog-to-digital conversion front ends
• Precision threshold detection circuits

Comparators Procurement Notes

Verify the specific ordering suffix FK to confirm the 20-pin LCCC ceramic package configuration. Ensure procurement channels support military-grade components characterized for the -55°C to 125°C operating range. Confirm RoHS status and lead finish specifications align with assembly requirements, as indicated by the SNPB designation in official documentation.

Comparators Selection Notes

Select this component when operation across the full military temperature spectrum (-55°C to 125°C) is mandatory. The FK package provides a robust ceramic housing suitable for harsh environments. Verify that the required supply voltage falls within the 4 V to 16 V range specified for the M grade. Consider the open-drain output topology when designing pull-up resistor networks for the target logic family.

Comparators Part Context

This part belongs to the TLC374 family of LinCMOS quadruple differential comparators manufactured by Texas Instruments. The 'M' suffix designates the military temperature grade, while 'FK' identifies the 20-pin ceramic chip carrier package. It shares functional similarities with other grades like TLC374C and TLC374I but offers extended thermal performance.
