Product details
Overview
TLV1704AMPWPSEP from Texas Instruments is a radiation-tolerant, microPower quad comparator in space-enhanced plastic TSSOP-14 packaging, operating from 2.2V to 24V supply, delivering 55µA per channel quiescent current, 300µV max input offset voltage, and 560ns propagation delay. It serves as a rail-to-rail input, open-collector output comparator for voltage monitoring and fault detection in satellite EPS and flight control units.
For engineers reviewing the TLV1704AMPWPSEP datasheet, TLV1704AMPWPSEP pinout, TLV1704AMPWPSEP application, or TLV1704AMPWPSEP equivalent, key selection considerations include SEL immunity to 43MeV-cm²/mg at 125°C, ELDRS-free performance to 30krad(Si), and open-collector outputs capable of sinking up to 24V above V– regardless of supply voltage.
Technical Context
The TLV1704AMPWPSEP implements four independent comparators with rail-to-rail input stages that prevent phase inversion when inputs exceed supply rails, enabling reliable signal detection near V+ and V–. Its open-collector outputs support wired-OR configurations (e.g., window comparators) and level-shifting to any rail up to 24V above the negative supply.
Designed for extended temperature operation (–55°C to 125°C), it features controlled baseline manufacturing, gold wire bonding, NiPdAu lead finish, and enhanced low-outgassing mold compound-meeting VID V62/18613 requirements for space-grade plastic packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.2V to 24V - supports wide-input systems including 28V avionics and 5V/12V subsystems without level shifting. |
| Quiescent Current (per channel) | 55µA - enables ultra-low-power system diagnostics in battery-backed or energy-constrained space payloads. |
| Input Offset Voltage | ±300µV max - ensures precise threshold detection in voltage monitors and zero-crossing circuits. |
| Propagation Delay | 560ns typical - provides fast response for real-time fault detection in command & data handling (C&DH) systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1704AMPWTPSEP | Same die, TSSOP-14 tape-and-reel (250 pcs); identical electrical specs and radiation ratings. | Optimized for automated SMT assembly; same space-enhanced plastic qualification. | Select when volume production and pick-and-place compatibility are required. |
| TLV1704-Q1 | Automotive-grade variant; AEC-Q100 qualified; 40krad(Si) TID not specified; no SEL immunity data published. | Targeted at automotive ADAS and infotainment; lacks space-specific radiation hardening documentation. | Use only in non-radiation environments where automotive qualification suffices and cost is prioritized. |
Compared with TLV1704AMPWPSEP, TLV1704AMPWTPSEP offers identical performance in tape-and-reel format for high-volume manufacturing, while TLV1704-Q1 trades space radiation assurance for automotive qualification-making TLV1704AMPWPSEP the sole choice for missions requiring verified 30krad(Si) RLAT and SEL immunity.

FAQ
What radiation hardness specifications apply to TLV1704AMPWPSEP?
TLV1704AMPWPSEP is rated for Single Event Latch-up (SEL) immunity to 43MeV-cm²/mg at 125°C, ELDRS-free performance to 30krad(Si), and Total Ionizing Dose (TID) radiation level assurance (RLAT) to 30krad(Si) per wafer lot. These values are verified per VID V62/18613 and documented in the official TI datasheet SLOSE29B.
Does TLV1704AMPWPSEP support rail-to-rail input operation?
Yes, TLV1704AMPWPSEP features a rail-to-rail input stage with common-mode voltage range from V– to V+, enabling direct sensing of signals at either supply rail without phase inversion or input clamping artifacts. This is confirmed in Section 6.3.1 of the TLV1704AMPWPSEP datasheet.
What is the maximum output sink voltage capability of TLV1704AMPWPSEP?
TLV1704AMPWPSEP's open-collector outputs can sink up to 24V above the negative supply (V–), regardless of the device's own supply voltage. This allows level-shifting to higher-voltage buses-for example, interfacing with 28V avionics logic-without additional level translators.
Is TLV1704AMPWPSEP pin-compatible with commercial TLV1704 variants?
Yes, TLV1704AMPWPSEP shares identical TSSOP-14 pinout and electrical behavior with commercial TLV1704 devices, but adds space-enhanced plastic construction, radiation testing, and extended temperature qualification. Pin-for-pin compatibility is maintained per TI's package drawing PW0014A.
What temperature range is TLV1704AMPWPSEP specified for?
TLV1704AMPWPSEP is fully specified from –55°C to 125°C, covering the full operational envelope required for spacecraft thermal cycling, launch vibration, and orbital thermal extremes. This range is validated across all electrical parameters in the datasheet's Recommended Operating Conditions table.
