TLC354CD

Comparators Overview

The TLC354CD is a quad differential comparator fabricated using LinCMOS technology, housed in a 14-pin SOIC package. It operates from a single or dual supply with a voltage range of 1.4 V to 16 V. Key electrical characteristics include a typical input bias current of 5 pA and an input offset voltage of 2 mV at 25°C. The device features n-channel open-drain outputs compatible with TTL, MOS, and CMOS logic levels. It is characterized for operation within the commercial temperature range of 0°C to 70°C.

Comparators Feature Summary

• LinCMOS fabrication enables extremely high input impedance and low power consumption suitable for battery applications.
• N-channel open-drain output configuration supports positive-logic wired-AND relationships.
• Built-in electrostatic discharge protection circuits provide robust handling reliability.

Comparators Applications

• Low-voltage battery-powered systems
• Direct interface to high-impedance signal sources
• General-purpose voltage threshold detection

Comparators Procurement Notes

Verify the specific suffix 'CD' confirms the SOIC package and commercial temperature grade (0°C to 70°C). Confirm RoHS compliance and lead finish status via the latest manufacturer documentation. Ensure the ordering part number matches the required pin count and package dimensions for PCB layout compatibility.

Comparators Selection Notes

Select this component when multiple independent differential comparisons are required in a compact surface-mount footprint. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate the 1.4 V minimum supply voltage against system power constraints. Verify that the 16 V maximum rating aligns with the application's input signal levels.

Comparators Part Context

This device belongs to the TLC354 family of quadruple differential comparators. Variants such as the TLC354ID and TLC354M offer extended industrial and military temperature ranges respectively. The family utilizes Texas Instruments' proprietary LinCMOS process to achieve superior input impedance compared to standard bipolar comparators.

Comparators Replacement Considerations

TLC354CN provides identical functionality in a PDIP package. TLC354CPW offers the same electrical performance in a TSSOP package. Cross-reference pinouts and thermal dissipation ratings when substituting packages.
