Product details
Overview
TLV1704AIPW from Texas Instruments is a quad, rail-to-rail input, open-collector comparator operating from 2.2 V to 36 V (±1.1 V to ±18 V), delivering 55 µA per channel quiescent current, 560 ns low-to-high propagation delay at 2.2 V, and 300 µV typical input offset voltage. It enables overvoltage detection in industrial power supplies with precise thresholding and wide common-mode range.
For engineers reviewing the TLV1704AIPW datasheet, TLV1704AIPW pinout, TLV1704AIPW application, or TLV1704AIPW equivalent, key selection considerations include its TSSOP-14 package, –40°C to +125°C temperature rating, rail-to-rail input stage, open-collector output compatible with up to +36 V pull-up, and stable propagation delay across temperature.
Technical Context
The TLV1704AIPW integrates four independent comparators sharing a common supply domain, each featuring a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails. Its open-collector outputs support wired-OR configurations essential for window comparators and level translation.
Propagation delay remains stable across temperature (–40°C to +125°C) and supply voltage (2.2 V to 36 V), with measured tPLH = 560 ns and tPHL = 460 ns at 100 mV overdrive and 2.2 V supply. Input common-mode range spans from V– to V+, enabling direct sensing near ground or high-side rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.2 V to +36 V or ±1.1 V to ±18 V - supports single-supply battery-powered systems and dual-supply industrial control rails. |
| Quiescent Current | 55 µA per channel - enables always-on monitoring in energy-constrained applications without compromising response time. |
| Propagation Delay | 560 ns (low-to-high), 460 ns (high-to-low) at 100 mV overdrive - ensures fast fault detection in overvoltage/undervoltage protection circuits. |
| Input Offset Voltage | ±300 µV typical at 25°C - provides accurate threshold discrimination for precision window and zero-crossing detection. |
| Input Common-Mode Range | V– to V+ - allows direct connection to signals referenced to ground or high-side rails without level-shifting circuitry. |
| Output Type | Open-collector - permits flexible pull-up to any voltage ≤ +36 V above V–, enabling interface with 3.3 V, 5 V, or 24 V logic domains. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor drives, and medical equipment environments. |
Pinout & Package
TSSOP-14 package (4.40 mm × 5.00 mm body size) with exposed pad for thermal performance; 14-pin surface-mount layout optimized for compact PCB designs requiring multiple threshold comparisons.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, channel 1 | Accepts reference or signal input; rail-to-rail capable, no phase inversion beyond supply rails. |
| 1IN– | Inverting input, channel 1 | Accepts monitored signal or reference; matched bias current minimizes offset error in differential sensing. |
| 1OUT | Open-collector output, channel 1 | Sinks current only; requires external pull-up resistor to define logic-high level and voltage domain. |
| 2IN+ | Noninverting input, channel 2 | Independent input path; identical electrical specs to channel 1 for multi-threshold system monitoring. |
| 2IN– | Inverting input, channel 2 | Enables dual-channel window comparator configuration when paired with channel 1 and shared pull-up. |
| 2OUT | Open-collector output, channel 2 | Wired-OR compatible; used with 1OUT to generate composite alarm signals without additional logic gates. |
| 3IN+, 3IN–, 3OUT | Channel 3 inputs and output | Full functional replication for third independent comparison function within same footprint. |
| 4IN+, 4IN–, 4OUT | Channel 4 inputs and output | Enables four distinct voltage thresholds or fault conditions monitored simultaneously on one IC. |
| V+ | Positive supply pin | Connects to highest potential rail; supports up to +36 V, enabling direct interface with 24 V industrial buses. |
| V– | Negative supply pin | Connects to lowest potential rail (GND or negative supply); defines reference for all internal circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables direct sensing of signals at GND or V+ without attenuation or clipping-critical for low-voltage battery monitoring. |
| 55 µA per channel quiescent current | Reduces total system standby power by >70% versus legacy comparators, extending battery life in portable diagnostics. |
| Stable propagation delay vs. temperature | Varies <±10% from –40°C to +125°C-ensures consistent timing margins in thermal-cycling environments like motor controllers. |
| Open-collector output with 36 V tolerance | Allows single TLV1704AIPW to drive mixed-voltage subsystems (e.g., 3.3 V MCU + 24 V relay coil) using separate pull-ups. |
| –40°C to +125°C industrial temperature grade | Validated operation across full range without derating-eliminates need for thermal margining in outdoor or engine-compartment designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher 1.5 mA quiescent current per channel; 1.3 µs propagation delay; no rail-to-rail input; SOIC-14 package. | Not suitable for battery-powered or low-offset precision applications; limited to 36 V max supply but no 36 V output tolerance. | Choose LM339DR only when cost is primary constraint and power/precision requirements are relaxed. |
| TLV3704IPW | Nanopower (1.3 µA/channel); push-pull output; 360 ns propagation delay; same TSSOP-14 package. | Push-pull eliminates external pull-up but limits output voltage to V+; unsuitable for mixed-voltage interfacing. | Choose TLV3704IPW when ultra-low power dominates and output must drive CMOS loads directly without pull-up resistors. |
Compared with LM339DR, TLV1704AIPW delivers 27× lower supply current and 2.3× faster response with rail-to-rail input; compared with TLV3704IPW, it trades 43× higher quiescent current for 36 V output compatibility and robustness in industrial wiring environments.

FAQ
What is the maximum supply voltage rating for TLV1704AIPW?
The TLV1704AIPW has an absolute maximum supply voltage of +40 V (±20 V), but its recommended operating range is +2.2 V to +36 V (±1.1 V to ±18 V). Operation above +36 V risks permanent damage and invalidates parametric guarantees. Always use 0.1-µF ceramic bypass capacitors at V+ and V– pins to suppress transients that could exceed this limit.
Does TLV1704AIPW support dual-supply operation?
Yes, TLV1704AIPW supports dual-supply operation from ±1.1 V to ±18 V. The V+ pin connects to the positive rail and V– to the negative rail; inputs and outputs are referenced to this split supply. The rail-to-rail input stage accepts signals from V– to V+, making it suitable for bipolar signal conditioning in instrumentation amplifiers and sensor front-ends.
Can TLV1704AIPW outputs be pulled up to 24 V while powered from 5 V?
Yes, TLV1704AIPW open-collector outputs tolerate pull-up voltages up to +36 V above V–, regardless of the IC's own supply voltage. When powered from 5 V (V+ = 5 V, V– = GND), its outputs can safely interface with 24 V logic or relay drivers using an external 24 V pull-up resistor-enabling mixed-voltage system design without level translators.
What is the input offset voltage drift specification for TLV1704AIPW?
The TLV1704AIPW exhibits ±4 µV/°C to ±20 µV/°C input offset voltage drift over –40°C to +125°C, with typical performance near ±10 µV/°C. This drift contributes directly to threshold error in precision monitoring applications; for example, a 100°C ambient shift may introduce up to ±2 mV offset change-within acceptable limits for most industrial voltage supervision tasks.
Is TLV1704AIPW pin-compatible with other quad comparators in TSSOP-14?
No, TLV1704AIPW is not pin-compatible with generic TSSOP-14 quad comparators such as LM339DR or TLC3704. Its pinout (e.g., 1IN+, 1IN–, 1OUT, 2IN+, 2IN–, 2OUT, etc.) follows Texas Instruments' TLV170x family layout and differs from industry-standard arrangements. PCB redesign is required when substituting into existing LM339-based layouts.
