Product details
Overview
TLC3704IPWR from Texas Instruments is a quad micropower LinCMOS voltage comparator IC designed for single-supply operation (3 V to 16 V), delivering ±8 mA push-pull CMOS output drive without external pullup resistors, 2.7 µs typical propagation delay (tPLH) with 5-mV overdrive, and only 200 µW typical supply power at 5 V. It serves as a low-power, high-precision replacement for LM339 in battery-powered sensor interfaces and industrial monitoring systems.
For engineers reviewing the TLC3704IPWR datasheet, TLC3704IPWR pinout, TLC3704IPWR application, or TLC3704IPWR equivalent, key selection factors include its industrial temperature range (−40°C to 85°C), rail-to-rail input capability (0 V to VDD − 1.5 V), 5-mV max input offset voltage, and compatibility with TTL and HCMOS logic families.
Technical Context
The TLC3704IPWR integrates four independent comparators on a single die using Texas Instruments' LinCMOS process, combining high input impedance (>1012 Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage across temperature. Its push-pull output stage eliminates external pullup components while maintaining full TTL logic compatibility and driving capacitive loads up to 50 pF directly.
Designed for single-supply systems, it supports common-mode input voltages from −0.2 V to VDD − 1.5 V and exhibits 84 dB typical CMRR and 85 dB kSVR at 25°C - enabling reliable operation in noisy industrial environments where supply and common-mode variations are present.
Key Specifications

Pinout & Package
TLC3704IPWR uses a 14-pin TSSOP (PW) package with 5.0 mm × 6.4 mm footprint and 0.65 mm pitch, optimized for automated assembly and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 12, 13, 14 | No internal connection (NC) | Unused pins; must be left floating or tied to GND per layout best practice - no electrical function. |
| 3, 4, 10, 11 | Comparator Inputs (IN−, IN+) | Differential input pairs for each of four comparators - support rail-to-rail common-mode range down to −0.2 V. |
| 7, 8, 9, 13 | Comparator Outputs (OUT) | Push-pull CMOS outputs - actively drive high/low without pullup resistors; compatible with TTL and CMOS loads. |
| 14 | VDD | Positive supply pin - accepts 3 V to 16 V; decoupling capacitor required within 1 cm for stability. |
| 7 | GND | Ground reference - shared return path for all four comparators and output stages. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher supply current (500 µA typ), open-collector outputs requiring pullup resistors, slower tPLH (1.3 µs min but higher variation). | Requires external pullups; less suitable for ultra-low-power or space-constrained designs. | Choose LM339DR only if legacy design reuse or cost sensitivity outweighs power and layout advantages of TLC3704IPWR. |
| TLC372CPW | Dual-channel version (2 comparators), identical LinCMOS specs, same PW package, lower channel count. | Not drop-in for quad-channel needs; requires two devices or redesign for 4-input systems. | Select TLC372CPW only when exactly two comparators are needed - avoids over-provisioning and reduces cost per channel. |
Compared with LM339DR and TLC372CPW, the TLC3704IPWR uniquely delivers quad-channel micropower performance in a single TSSOP package with integrated push-pull outputs - reducing bill-of-materials, PCB area, and system-level power consumption without sacrificing speed or precision.

FAQ
What is the maximum operating supply voltage for the TLC3704IPWR?
The TLC3704IPWR supports a supply voltage range of 3 V to 16 V, with absolute maximum rating at 18 V. Operation above 16 V risks exceeding recommended conditions and may impact reliability or parametric performance. For 12-V systems, the TLC3704IPWR operates safely with margin; always include a 100-nF ceramic decoupling capacitor near the VDD pin.
Does the TLC3704IPWR require external pullup resistors on its outputs?
No, the TLC3704IPWR features push-pull CMOS outputs that actively drive both high and low states - eliminating the need for external pullup resistors. This reduces component count, board space, and power dissipation. Each output can source or sink ±8 mA, making it fully compatible with TTL and CMOS logic families without additional buffering.
What is the input common-mode voltage range of the TLC3704IPWR?
The TLC3704IPWR supports an input common-mode voltage range from −0.2 V to VDD − 1.5 V across its full operating temperature range (−40°C to +85°C). At 25°C, the range extends to 0 V to VDD − 1 V. This rail-to-rail capable input allows direct interfacing with sensors and references referenced to ground or VDD without level-shifting circuitry.
How does the TLC3704IPWR compare to the LM339 in terms of power consumption?
The TLC3704IPWR consumes only 200 µW typical at 5 V (35–80 µA supply current), roughly 1/20th the power of the LM339 (≈4 mW). This dramatic reduction enables use in energy-harvesting and battery-operated systems where standby current is critical. The TLC3704IPWR achieves this without sacrificing speed - its 2.7 µs tPLH is competitive with LM339's typical 1.3 µs, but with far better consistency and lower temperature drift.
Is the TLC3704IPWR pin-compatible with other packages in the TLC3704 family?
The TLC3704IPWR (TSSOP-14) shares identical pinout with the TLC3704ID (SOIC-14) and TLC3704IN (PDIP-14), including VDD (pin 14), GND (pin 7), and all comparator inputs/outputs. However, NC pins differ slightly between packages - verify mechanical layout and thermal pad presence (TSSOP has exposed pad) before substitution. Electrical behavior is identical across packages.
