Overview

Description

ISL4221EIRZ is an Intersil/Renesas dual digital buffer/driver in an 8‑pin package. The “E” variant typically denotes extended-temperature operation, and “IRZ” is the RoHS‑compliant package code. It provides two independent, non‑inverting buffers with tri‑state enable pins, useful for fan‑out, buffering, or small level‑shifting tasks in digital logic.
Key points:
- Two buffers with separate enable controls
- TTL/CMOS input compatibility
- Usable with common logic supplies (3.3 V or 5 V; check the exact Vcc range in the datasheet)
- Low propagation delay and defined drive to buffer loads
Typical uses: microcontroller I/O buffering, clock or signal distribution, and general-purpose buffering in mixed‑signal designs.
How to use: connect Vcc and GND, drive inputs from your source, and use the enables to activate/deactivate each output. For precise specs (Vcc range, thresholds, propagation delay, drive current, pinout), consult the latest ISL4221E data sheet and packaging details.

Features

I don’t have the exact datasheet memorized. Here are the typical features you’d expect for the ISL4221EIRZ family (dual differential line transceiver) – please verify with the official datasheet:
- Dual differential input/output channels
- Wide supply range (commonly 2.7 V to 5.5 V)
- TTL/CMOS-compatible outputs
- ESD protection on inputs/outputs
- Small Pb-free package (IRZ) with 8 pins
- Low power/low quiescent current variants
For precise specs (propagation delay, common-mode ranges, output swing, enable/shutdown behavior, exact package, and ordering options), please share the datasheet or allow me to fetch it.

Package

ISL4221EIRZ is in an 8‑pin small‑outline package (SOIC, 8‑lead). Pb‑free/RoHS compliant.

Pinout

Pin count: 8 pins (ISL4221EIRZ is an 8-pin device, typically in an MSOP-8/SOIC-8 package).
Function: Dual high-speed buffer/driver with enable (general-purpose line driver), often used as a buffer or level-shifting buffer between voltage domains.

Manufacturer

Manufacturer: Renesas Electronics Corporation (Intersil brand).
Type of company: A Japanese multinational semiconductor company that designs and sells analog, mixed-signal, and power-management integrated circuits.

Application

Typical applications:
- High-speed differential serial interfaces (RS-422/485, LVDS/PECL/CML)
- Backplanes and interconnects
- Networking and telecom equipment
- Industrial automation and instrumentation
- Automotive data links
- Medical electronics
- Video/data transmission front-ends requiring robust differential signaling
