Description
ISL4221EIRZ is an Intersil (now Renesas) RS-422/RS-485 transceiver in an 8-pin package. It provides one driver and one receiver to connect a microcontroller to RS-422/RS-485 networks. Key features typically include 5V operation (with 3.3V logic variants), DI (driver input) and RO (receiver output) with DE (driver enable) and RE (receiver enable) controls, differential A/B outputs, a failsafe receiver (RO stays high if the bus is idle or open), low power, and ESD protection. The EIRZ suffix denotes the RoHS-compliant, tape-and-reel/packaging variant. Common applications are industrial fieldbuses, long-distance data links, and multi-point networks. For exact electrical specs, timing, and pinout, consult the datasheet.
Pinout
8 pins. It is a dual, non-inverting clock buffer/fanout driver with enable (tri-state outputs), used to distribute a single clock to two low-skew outputs. Package: MSOP-8/TSSOP-8 (IRZ).
Manufacturer
The ISL4221EIRZ is manufactured by Renesas Electronics (Intersil). Intersil was acquired by Renesas in 2017. Renesas is a multinational semiconductor company based in Japan that designs and manufactures analog and mixed-signal ICs, including power-management, interface, and timing products.
Application
ISL4221EIRZ is a high-speed differential clock fan-out/buffer. Typical application areas include:
- Low-skew, low-jitter clock distribution for FPGA, ASIC, and DSP clocks
- Differential clock buffering for LVDS/other differential clock networks
- Telecom and networking equipment requiring precise timing
- Video, imaging, and multimedia systems needing synchronized clocks
- Instrumentation and data-acquisition systems with multiple phase-aligned clock outputs
- Embedded systems requiring multiple, reliable clock outputs with enable/disable control
- Low-skew, low-jitter clock distribution for FPGA, ASIC, and DSP clocks
- Differential clock buffering for LVDS/other differential clock networks
- Telecom and networking equipment requiring precise timing
- Video, imaging, and multimedia systems needing synchronized clocks
- Instrumentation and data-acquisition systems with multiple phase-aligned clock outputs
- Embedded systems requiring multiple, reliable clock outputs with enable/disable control
Package
ISL4221EIRZ comes in an 8‑lead SOIC (SOIC-8) package.
