Product details

Overview

TLV1704AIPWR from Texas Instruments is a quad, rail-to-rail input, open-collector microPower 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, 300 µV typical input offset voltage, and –40°C to +125°C industrial temperature range. It enables overvoltage detection in industrial power supplies with precise threshold sensing.

For engineers reviewing the TLV1704AIPWR datasheet, TLV1704AIPWR pinout, TLV1704AIPWR application, or TLV1704AIPWR equivalent, key selection criteria include supply voltage flexibility (2.2–36 V), rail-to-rail input common-mode range, open-collector output compatibility with 36 V pull-up, low propagation delay vs. temperature stability, and TSSOP-14 package thermal performance for high-density PCB layouts.

Technical Context

The TLV1704AIPWR implements four independent comparators sharing a single dual-supply or single-supply rail configuration, each featuring rail-to-rail input stages that prevent phase inversion when inputs exceed supply rails. Its open-collector outputs support wired-OR logic and flexible level-shifting up to 36 V above the negative supply.

Propagation delay remains stable across –40°C to +125°C, with 460 ns high-to-low and 560 ns low-to-high delays measured at 100 mV overdrive and 15 pF load. Input bias current stays below 20 nA over full temperature range, enabling high-impedance sensing in battery-powered and industrial monitoring systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad open-collector comparator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM339DR	Higher quiescent current (500 µA/channel), wider offset (±2 mV), slower delay (1.3 µs), no rail-to-rail input - requires input attenuation for >24 V rails.	Acceptable for cost-sensitive 5 V/12 V systems where speed and precision are secondary; not suitable for battery-powered or high-accuracy window detection.	Select LM339DR only when legacy design reuse or lowest unit cost is primary; verify input voltage scaling and thermal derating for >85°C operation.
TLV3704IPW	Push-pull output (no external pull-up needed), lower quiescent current (350 nA/channel), nanopower domain - lacks 36 V output tolerance and rail-to-rail input beyond ±15 V.	Better for ultra-low-power wake-up circuits or coin-cell devices; incompatible with 24 V logic interfacing or high-side sensing above 15 V.	Choose TLV3704IPW for always-on sensor nodes requiring <1 µA total system standby; avoid where open-collector wiring or >15 V signal handling is required.

Compared with LM339DR and TLV3704IPW, TLV1704AIPWR uniquely balances low power (55 µA), high voltage capability (36 V tolerant output), rail-to-rail input, and industrial temperature range - making it optimal for next-generation programmable logic controllers and modular power system monitors.

FAQ

What is the maximum supply voltage rating for TLV1704AIPWR?

The absolute maximum supply voltage for TLV1704AIPWR is +40 V (or ±20 V), but the recommended operating range is +2.2 V to +36 V (±1.1 V to ±18 V). Exceeding 40 V risks permanent damage. Operation at 36 V is fully specified across –40°C to +125°C, with all electrical characteristics validated per SBOS589D datasheet revision D.

Does TLV1704AIPWR support true rail-to-rail input operation?

Yes, TLV1704AIPWR supports rail-to-rail input common-mode range from V– to V+, including both supply rails. The input stage is designed to prevent phase inversion even when inputs exceed V+ or fall below V– by up to 0.5 V, as confirmed in Figure 18 of the SBOS589D datasheet.

Can TLV1704AIPWR drive a 24 V logic input directly?

Yes, TLV1704AIPWR's open-collector output can sink current with VPULLUP up to 36 V above V–, enabling direct interface to 24 V logic inputs using an external pull-up resistor. The output is rated for 20 mA short-circuit current and maintains valid logic levels across the full industrial temperature range.

What is the typical propagation delay of TLV1704AIPWR at 5 V supply?

At VS = 5 V, TA = 25°C, CL = 15 pF, and 100 mV input overdrive, TLV1704AIPWR exhibits 560 ns typical low-to-high (tPLH) and 460 ns typical high-to-low (tPHL) propagation delay. These values are stable across temperature, varying less than ±10% from –40°C to +125°C per Figure 10 in SBOS589D.

Is TLV1704AIPWR pin-compatible with other quad comparators in TSSOP-14?

No, TLV1704AIPWR has a unique pinout defined in Section 6 of SBOS589D and is not pin-compatible with generic TSSOP-14 quad comparators like LM339 or TLC3704. Its pin mapping (e.g., V+ on pin 3, V– on pin 8 and 12, 4OUT on pin 13) must be verified against the official TI datasheet before PCB layout.
