Product details
Overview
TLC3704CPW from Texas Instruments is a quad micropower LinCMOS voltage comparator with push-pull CMOS outputs, designed for single-supply operation from 3 V to 16 V, delivering ±8 mA output drive, 2.7 µs typical propagation delay (tPLH) at 5-mV overdrive, and 200 µW typical supply power at 5 V. It serves in precision threshold detection circuits within battery-powered instrumentation and low-power sensor interfaces.
For engineers reviewing the TLC3704CPW datasheet, TLC3704CPW pinout, TLC3704CPW application, or TLC3704CPW equivalent, key selection considerations include its rail-to-rail input common-mode range (0 V to VDD − 1.5 V), ultra-low input bias current (5 pA typ at 25°C), absence of external pullup requirements, and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The TLC3704CPW integrates four independent comparators on a LinCMOS process, enabling stable input offset voltage (1.2–5 mV max at 25°C) and high CMRR (84 dB) across temperature. Its push-pull output stage eliminates need for external pullup resistors while maintaining TTL-compatible logic levels and driving capacitive loads directly.
It supports single-supply operation with input common-mode range extending to GND and within 1.5 V of VDD, and features on-chip ESD protection rated to 2 kV HBM. The device is characterized for 0°C to 70°C operation and exhibits supply current as low as 35 µA (typ) per comparator set under no-load conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Open-collector output; requires external pullup; higher supply current (500 µA typ); wider offset (±2 mV min, ±30 mV max) | Compatible where board space allows pullup resistors and speed >5 µs is acceptable | Select LM339DR only if legacy design reuse or cost sensitivity outweighs power and layout advantages of TLC3704CPW |
| TLC372CPW | Dual-channel version in same TSSOP-8 package; identical electrical specs except channel count and pinout | Applicable when only two comparators are needed and footprint reduction is critical | Choose TLC372CPW for space-constrained dual-comparator functions; TLC3704CPW remains optimal for quad-channel density |
Compared with LM339DR, TLC3704CPW reduces system power by >90% and eliminates four pullup resistors; versus TLC372CPW, it delivers double channel count in only +2 mm² PCB area, making it superior for compact quad-threshold designs.

FAQ
What is the maximum operating temperature range for the TLC3704CPW?
The TLC3704CPW is characterized for operation from 0°C to 70°C (commercial grade). It is not rated for extended industrial (−40°C to 85°C) or military (−55°C to 125°C) ranges - those require TLC3704IPW or TLC3704MPW variants. Operating outside 0°C–70°C may cause parameter drift beyond datasheet limits, including increased input offset voltage and reduced CMRR.
Does the TLC3704CPW require external pullup resistors on its outputs?
No, the TLC3704CPW does not require external pullup resistors. Its push-pull CMOS output stage actively drives both high and low states, delivering ±8 mA output current. This eliminates the need for pullup resistors, reducing power dissipation, board space, and component count - a key differentiator from open-collector comparators like the LM339.
Can the TLC3704CPW operate from a 3.3-V supply?
Yes, the TLC3704CPW supports 3 V minimum supply voltage and is fully functional at 3.3 V. At this voltage, it maintains 5 pA typical input bias current, 2.7 µs tPLH (with appropriate overdrive), and rail-to-rail input capability down to GND. Output high-level voltage (VOH) is ≥3.0 V at IOH = −4 mA, ensuring reliable interfacing with 3.3-V logic families.
What is the input common-mode voltage range of the TLC3704CPW?
The TLC3704CPW accepts input voltages from 0 V up to VDD − 1.5 V across its full operating temperature range (0°C to 70°C). At 25°C, the range extends to VDD − 1 V. This rail-to-rail input capability enables direct connection to grounded sensors, resistive dividers, and current-sense amplifiers without level-shifting circuitry.
How does the TLC3704CPW handle electrostatic discharge (ESD)?
The TLC3704CPW integrates Texas Instruments' patented LinCMOS ESD-protection circuitry, qualified to 2 kV HBM (100 pF/1.5 kΩ) and 200 V CDM. This on-chip protection safely shunts ESD transients without introducing significant leakage current (<1 nA post-event), preserving the device's 5 pA input bias specification and eliminating need for external ESD components in most board-level implementations.
