Renesas ISL55141IVZ

Overview

ISL55141IVZ from Intersil is a single-channel, high-speed 18V CMOS window comparator with dual independent thresholds (CVA0/CVB0), three-state output qualification (QA0/QB0), and 9.5ns typical propagation delay. It operates across ±3V to ±9V split supplies or 10–18V single supply, supports TTL/ECL/CMOS/LVDS input families, and delivers user-defined VOH/VOL logic levels for direct interfacing with test controllers. Used in burn-in ATE systems for Flash device voltage supervision.

For engineers reviewing the ISL55141IVZ datasheet, ISL55141IVZ pinout, ISL55141IVZ application, or ISL55141IVZ equivalent, this page provides verified technical context, exact pin functions, real-world use cases, and validated alternative options - all grounded in FN6230 Rev 4.00 and official Intersil package documentation for the 14-lead TSSOP variant.

Technical Context

The ISL55141IVZ implements a dual-threshold window comparator architecture where VINP0 is compared against CVA0 (high threshold) and CVB0 (low threshold), generating two digital outputs QA0 and QB0 that encode input state as Valid Low (0,0), Invalid (0,1), or Valid High (1,1). Its high-voltage CMOS process enables rail-to-rail common-mode input range (VEE to VCC−5V) and 13V input swing capability.

Output logic levels are set externally via unbuffered VOH and VOL pins, allowing full compatibility with system controller I/O rails (e.g., 5V VOH / 0V VOL). Power-down is controlled by the PD pin, reducing supply current from ~12.5mA per comparator to <10µA within 10µs, with 15µs wake-up time.

Key Specifications

Pinout & Package

ISL55141IVZ uses a 14-lead Thin Shrink Small Outline Package (TSSOP), Pb-free, with thermal pad electrically tied to VEE. Pin 1 is marked with an index area; lead pitch is 0.65mm; body dimensions are 5.00×4.40×1.20mm (L×W×H).

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-threshold comparator applications.

Compared with TLV3601DR and MAX961ESA+, the ISL55141IVZ uniquely supports 18V operation, dual independent thresholds, and programmable VOH/VOL - making it irreplaceable in high-voltage ATE and Flash supervisory roles where those features are mandatory.

FAQ

What is the function of the PD pin on the ISL55141IVZ?

The PD (Power-Down) pin on the ISL55141IVZ controls standby mode: when driven to VCC, it reduces total supply current to <10µA; when tied to VEE, the device operates normally. The ISL55141IVZ exits power-down in 15µs and enters it in 10µs, supporting burst-mode ATE operation without firmware overhead.

Can the ISL55141IVZ accept input voltages below ground?

Yes - the ISL55141IVZ supports input common-mode range from VEE to VCC−5V, and its absolute maximum rating allows VINPX down to (VEE −0.5V). When VEE = −3V, inputs as low as −3.5V are permissible, enabling direct monitoring of negative-bias rails in Flash testers without level-shifting circuitry.

How are VOH and VOL used in the ISL55141IVZ?

VOH and VOL are unbuffered analog supply inputs that define the high and low output voltage levels for QA0 and QB0. For example, connecting VOH to +5V and VOL to 0V configures both outputs to swing between 0V and 5V - matching standard TTL/CMOS logic levels regardless of VCC/VEE values. The ISL55141IVZ requires external sources capable of supplying sufficient current to these pins under load.

What package type does the ISL55141IVZ use?

The ISL55141IVZ uses a 14-lead Thin Shrink Small Outline Package (TSSOP), designated M14.173 per Intersil's ordering information. It features a 0.65mm lead pitch, 5.00×4.40mm body, and Pb-free RoHS-compliant construction. Unlike the QFN variants (e.g., ISL55141IRZ), the ISL55141IVZ has gull-wing leads for standard reflow assembly.

Is the ISL55141IVZ still in active production?

No - according to Intersil's FN6230 Rev 4.00 datasheet (August 2015), the ISL55141IVZ is marked "No longer available or supported" in the Ordering Information table. However, Aetrix Electronics maintains legacy inventory and offers lifecycle management support, including obsolescence forecasting and cross-reference guidance for migration paths.
