Product details
Overview
TLC354ID from Texas Instruments is a LinCMOS™ quadruple differential comparator IC designed for precision voltage comparison in single- or dual-supply systems. It features 5 mV max input offset voltage, 5 pA typical input bias current, and operates from 1.4 V to 16 V supply - enabling use in low-voltage battery-powered instrumentation and industrial sensor interfaces.
For engineers reviewing the TLC354ID datasheet, TLC354ID pinout, TLC354ID application, or TLC354ID equivalent, key selection criteria include its industrial temperature range (–40°C to +85°C), open-drain n-channel outputs compatible with TTL/MOS/CMOS, and pin compatibility with LM339 for drop-in replacement in legacy designs.
Technical Context
The TLC354ID implements four independent comparators on a single die using LinCMOS™ process technology, delivering ultra-high input impedance (>10¹² Ω) and sub-picoampere input bias current. Each comparator supports common-mode input voltage down to ground and up to VDD–1.5 V at full temperature range.
Its open-drain output stage enables wired-AND logic configurations and direct interfacing with multiple logic families. The device includes built-in ESD protection rated at 2000 V per MIL-STD-833C Method 3015, and exhibits ultrastable offset drift of typically 0.23 µV/month including first 30 days.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher input offset voltage (7 mV max), higher supply current (500 µA typ), BJT input stage. | Limited to 0°C to +70°C; less suitable for low-power or extended-temperature deployments. | Select when cost is primary constraint and industrial temp range or ultra-low IIB are not required. |
| TLC3704CDR | CMOS inputs, lower supply current (40 µA typ), but narrower supply range (3 V to 16 V). | No 1.4 V operation; lacks ESD rating documentation; not specified for –40°C operation. | Select for ultra-low-power applications above 3 V where offset drift and ESD robustness are secondary concerns. |
Compared with LM339DR and TLC3704CDR, the TLC354ID uniquely combines industrial temperature rating, 1.4 V minimum supply, 5 pA input bias, and documented 2000 V HBM ESD protection - making it optimal for ruggedized, battery-operated sensor systems requiring long-term stability.

FAQ
What is the operating temperature range of the TLC354ID?
The TLC354ID is characterized for industrial operation from –40°C to +85°C. This rating is verified per the manufacturer's test conditions and applies across the full specified supply voltage range (1.4 V to 16 V). The device maintains its 5 mV maximum input offset voltage and 300 µA typical supply current within this range, making it suitable for deployment in harsh environments such as factory floors or outdoor metering enclosures.
Does the TLC354ID support single-supply operation?
Yes, the TLC354ID fully supports single-supply operation with VDD referenced to ground (pin 10). Its common-mode input voltage range includes ground (0 V) and extends up to VDD–1.5 V across the full industrial temperature range. This allows direct interfacing with ground-referenced sensors and eliminates the need for dual supplies in most monitoring applications.
What logic families are compatible with the TLC354ID outputs?
The TLC354ID features open-drain n-channel outputs that are explicitly compatible with TTL, MOS, and CMOS logic families. External pull-up resistors must be used to establish the logic high level, which can be tied to VDD or a separate logic rail - enabling seamless level translation between different voltage domains in mixed-signal systems.
Is the TLC354ID pin-compatible with the LM339?
Yes, the TLC354ID is pin-compatible with the LM339 in the SOIC-14 (D) package. Both devices share identical pin assignments for inputs, outputs, VDD, and GND. This allows direct substitution in existing designs without PCB modification, though designers should verify that the TLC354ID's lower input bias current and wider supply range meet system requirements.
What is the maximum supply voltage for the TLC354ID?
The absolute maximum supply voltage for the TLC354ID is 18 V, but the recommended operating maximum is 16 V per the datasheet's "Recommended Operating Conditions" table. Operation at 16 V ensures compliance with all electrical specifications including input offset voltage, response time, and output drive capability across the full –40°C to +85°C temperature range.
