Product details
Overview
TS884IDT from STMicroelectronics is a quad nanopower rail-to-rail comparator with 220 nA typical supply current per operator at 1.2 V, 2 µs typical propagation delay, and operation from 1.1 V to 5.5 V. It features push-pull outputs, built-in input hysteresis (2.4 mV typ.), and operates across –40 °C to +125 °C - deployed in battery-powered medical sensors and automotive body control modules.
For engineers reviewing the TS884IDT datasheet, TS884IDT pinout, TS884IDT application, or TS884IDT equivalent, key selection criteria include ultra-low quiescent current under 1.2 V bias, rail-to-rail input common-mode range extending beyond rails, push-pull output drive capability without external pull-ups, and guaranteed performance over extended temperature.
Technical Context
The TS884IDT integrates four independent comparators on a single die, each with internally trimmed input offset voltage (±6 mV max) and 3 µV/°C drift. Its architecture supports direct interfacing with low-voltage microcontrollers and analog sensors due to rail-to-rail inputs and outputs capable of sourcing/sinking up to 1.7 mA at 1.2 V.
It employs a proprietary nanopower biasing scheme enabling stable operation down to 1.1 V while maintaining 50–78 dB CMRR and 65–80 dB supply voltage rejection across 1.2–5 V supply range. Hysteresis (1.5–4.2 mV) is fixed and internal, eliminating need for external feedback components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.1 V to 5.5 V - enables direct use with single-cell Li-ion, NiMH, or coin-cell batteries without regulation. |
| Supply current per comparator | 220 nA typ. at 1.2 V - extends multi-year battery life in always-on wake-up or threshold-detection circuits. |
| Propagation delay | 2.1 µs typ. (low-to-high, 100 mV overdrive) - supports fast edge detection in low-power signal conditioning paths. |
| Input offset voltage | ±6 mV max (–40 °C to +125 °C) - ensures reliable trip-point accuracy in precision voltage monitoring applications. |
| Input hysteresis | 2.4 mV typ. - suppresses noise-induced output oscillation without requiring external resistor networks. |
| Rail-to-rail input range | (VCC–) – 0.2 V to (VCC+) + 0.2 V - allows direct sensing of signals near supply rails, e.g., battery voltage near 0 V or VCC. |
| Output type | Push-pull - eliminates need for external pull-up resistors, reducing BOM count and power loss in high-impedance nodes. |
Pinout & Package
TS884IDT is housed in a 14-lead SOIC (SO14) package with standard 1.27 mm pitch, 8.55–8.75 mm length, and 3.80–4.00 mm width. The package is RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting input (IN–) | Accepts differential input signals; rail-to-rail common-mode range supports direct connection to sensor outputs or divider taps. |
| 2, 6, 10, 14 | Non-inverting input (IN+) | Paired with corresponding IN– for each comparator; hysteresis applied internally between these terminals. |
| 3, 7, 11, 12 | Output (OUT) | Push-pull CMOS output - drives logic inputs directly or switches small loads (≤1.7 mA sink/source at 1.2 V). |
| 4 | VCC+ | Positive supply terminal - accepts 1.1–5.5 V; decoupling capacitor recommended within 1 cm for stability. |
| 8 | VCC– / GND | Ground reference - must be connected to system ground; shared return path for all four comparators. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 220 nA per comparator at 1.2 V - reduces total system standby current below 1 µA in quad-channel wake-up circuits. |
| Built-in hysteresis | 2.4 mV typical - prevents chatter on slow-moving or noisy inputs without external components or layout overhead. |
| Rail-to-rail I/O | Inputs operate from VCC– – 0.2 V to VCC+ + 0.2 V; outputs swing within 35 mV of rails at 0.2 mA load - maximizes dynamic range in low-voltage systems. |
| Wide temperature range | Specified from –40 °C to +125 °C - qualified for under-hood automotive and industrial sensor nodes without derating. |
| ESD robustness | 8 kV HBM - withstands handling and board-level ESD events in portable and automotive assembly environments. |
Applications
| Portable Medical Sensors | Automotive Body Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3694IDR | Higher supply current (350 nA typ.), no internal hysteresis, open-drain outputs only | Requires external pull-ups and hysteresis resistors - increases BOM and layout complexity | Choose when higher speed (1.8 µs) and rail-to-rail output swing are prioritized over lowest possible current. |
| MAX9064ASA+ | Lower hysteresis (1.2 mV typ.), 360 nA supply current, SO14 package but not AEC-Q100 qualified | Lacks automotive qualification and extended temperature support (–40 °C to +105 °C only) | Prefer for commercial portable devices where cost is critical and AEC-Q100 compliance is unnecessary. |
Compared with TLV3694IDR and MAX9064ASA+, TS884IDT delivers lower quiescent current, integrated hysteresis, push-pull outputs, and full AEC-Q100 qualification - making it optimal for space-constrained, battery-critical, and automotive-grade designs requiring zero-compromise reliability.

FAQ
What is the maximum supply voltage for TS884IDT?
The absolute maximum supply voltage is 6 V, but the functional operating range is strictly 1.1 V to 5.5 V. Operation above 5.5 V risks permanent damage, and operation below 1.1 V results in undefined output behavior and increased propagation delay. Designers must ensure bypass capacitors and PCB layout maintain stable rail integrity within this window.
Does TS884IDT require external hysteresis components?
No - TS884IDT includes fixed internal hysteresis of 1.5–4.2 mV (typ. 2.4 mV), eliminating the need for external resistors. This simplifies PCB layout, reduces component count, and guarantees consistent noise immunity across temperature and supply voltage. External hysteresis is neither required nor recommended.
Can TS884IDT drive an LED directly?
No - its output can source/sink up to 1.7 mA at 1.2 V, insufficient for typical indicator LEDs (requiring ≥5 mA). However, it can directly drive MCU GPIO interrupt pins or logic-level MOSFET gates. For LED driving, pair with a discrete NPN transistor or dedicated LED driver IC.
Is TS884IDT qualified for automotive applications?
TS884IDT itself is not AEC-Q100 qualified; only the TS884IPT (TSSOP14) and TS884IQ4T (QFN16) variants carry AEC-Q100 Grade 2 qualification. TS884IDT (SO14) is rated for –40 °C to +125 °C and used in non-safety-critical automotive subsystems like infotainment or comfort modules where full qualification is not mandated.
