Detailed Description

Micropower quad comparator IC with a precision reference and push‑pull outputs, supplied in a 16‑lead SOIC package. It fits the Integrated Circuits category and Specialized ICs subcategory. Designed for low power, wide supply range, accurate threshold detection, and space‑efficient designs. For exact functionality and limits, always confirm with the datasheet.

Key Features

Four independent comparator channels

Built‑in precision voltage reference for stable thresholds

Very low supply current for battery‑friendly designs

Wide supply voltage range for flexible use

Push‑pull outputs, logic‑friendly levels

Rail‑to‑rail output swing

Compact 16‑lead SOIC

Commercial temperature range options

Key Advantages

Extends battery life through ultralow power

Simplifies design by integrating reference and comparators

Saves board space compared to discrete solutions

Improves reliability and accuracy in threshold detection

Works across common supply rails and mixed‑signal environments

Packaging

Type: SOIC narrow body

Case code: 609 (industry standard SOIC‑16 mechanical family)

Material: Molded epoxy over copper leadframe, lead‑free or SnPb finish depending lot

Size: Approx. body width 3.9 mm, length ~9.9 mm, lead pitch 1.27 mm (verify exact drawing)

Pin configuration: 16 pins; typical quad comparator pinout with IN+ and IN− pairs, four outputs, V+, GND, and reference pins (see datasheet for the exact pin map)

Thermal characteristics: Typical θJA around 100–120 °C/W on standard FR‑4 with minimal copper; actual values depend on board and airflow (see datasheet)

Electrical properties: Low quiescent current, mV‑level input offset, output swings near rails, input common‑mode includes ground, wide supply range; exact min/max limits are in the datasheet

Lifecycle

Status: Generally active in distribution and widely used. Not known to be nearing discontinuation.

Alternatives and equivalents (functionally similar; verify details before substitution):

- Analog Devices LT/LTC family: LTC1441, LTC1442 (related low‑power comparators; check channel count and features)

- Texas Instruments: TLV3704, TLV3404 (ultralow‑power quad comparators)

- Microchip: MCP6544 (low‑power quad comparator), or MCP6004 plus external reference for similar architecture

- ON Semiconductor: LM339 or LMV339 (quad comparators; different output stage and specs)

- STMicroelectronics: TS3704 (quad comparator)

Compatibility, pinout, voltage range, output type, and timing vary by model. For drop‑in or form‑fit‑function options, contact our sales team via the Y‑IC website for tailored recommendations.
