Overview
The ISL55143IRZ-T is a high-speed CMOS comparator manufactured by Renesas Electronics Corporation. It features four independent channels within a single package, designed for applications requiring rapid signal detection and processing. The device operates on a power supply voltage range of 10V to 18V. Key electrical specifications include a maximum input offset voltage of 50mV at -3V and 12V conditions, a maximum input bias current of 0.025µA under the same conditions, and a maximum propagation delay of 15ns. The component draws a maximum static current of 12.5mA. It is housed in a 36-wire Fine Pitch Quad Flat No-lead (WQFN) package with an exposed pad, specifically identified as a 36-TQFN (6x6) footprint, suitable for surface mount installation.
Feature Summary
- Integrates four independent high-speed comparator channels into a compact single package.
- Utilizes CMOS technology to achieve low input bias current and fast propagation delay characteristics.
- Designed for operation within a wide single-supply voltage range of 10V to 18V.
Applications
- High-speed data acquisition systems
- Video and audio signal processing circuits
- Precision threshold detection applications
Procurement Notes
Verify the specific ordering suffix and tape-and-reel quantity requirements directly with authorized distributors or the manufacturer before placing orders. Confirm that the 36-TQFN (6x6) package dimensions align with your PCB footprint design. Ensure compliance with RoHS and lead-free standards as specified in the official datasheet. Check for any recent lifecycle status updates, as availability may vary across regions and suppliers.
Selection Notes
Select this component when multiple independent comparison functions are required in a space-constrained design. The low input bias current makes it suitable for high-impedance sensor interfaces. Verify that the 15ns propagation delay meets the timing requirements of your specific application. Ensure the operating temperature range of -40°C to 85°C covers your environmental conditions. Consider the 36-TQFN package thermal performance if multiple channels are actively switching simultaneously.
Part Context
The ISL55143 belongs to the broader family of high-speed analog comparators produced by Renesas Electronics, formerly Intersil. This series focuses on providing multi-channel solutions for complex signal conditioning tasks. The TQFN packaging allows for efficient board space utilization compared to traditional DIP or SOIC packages. It serves as a bridge between general-purpose operational amplifiers and dedicated single-channel comparators, offering integrated functionality for system designers.
Replacement Considerations
Consult official Renesas documentation for qualified pin-to-pin replacements. Verify compatibility regarding supply voltage ranges, package dimensions, and electrical parameters such as propagation delay and input offset voltage before substituting.
