ISL32172EFVZ-T

Overview

The ISL32172EFVZ-T is a quad RS-422 driver integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data transmission rates up to 32 Mb/s. The device features four drivers with no receivers, drawing a typical operating supply current of 800 uA. It provides robust electrostatic discharge protection rated at +/- 15 kV according to the Human Body Model. The component is designed for industrial environments, functioning reliably across an extended temperature range from -40°C to +125°C. It is housed in a 16-lead TSSOP package.

Feature Summary

• Integrated quad differential line drivers compliant with RS-422 standards
• High electrostatic discharge immunity rated at +/- 15 kV HBM
• Extended industrial temperature operation capability up to +125°C
• Low power consumption suitable for battery-operated systems

Applications

• Industrial communication networks requiring high noise immunity
• Point-to-point or multi-drop serial data transmission systems
• Harsh environment instrumentation and control interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and moisture sensitivity level handling requirements prior to assembly. Ensure compliance with RoHS directives and check for end-of-life status or alternative sourcing options given potential discontinuation risks.

Selection Notes

Select this component when a quad RS-422 transmitter is required without integrated receivers. Consider the TSSOP-16 package constraints for PCB layout. Verify that the 32 Mb/s speed meets system timing requirements. Ensure the 3.0 V to 5.5 V supply range aligns with the target application's power architecture.

Part Context

This part belongs to the ISL32172E series of RS-422 interface devices. It serves as the driver-only variant within the family, complementing receiver or transceiver models. The suffix 'V' denotes the TSSOP package type, while 'Z' indicates lead-free composition. It is distinct from the ISL32173E series which offers higher speeds and combined driver/receiver functionality.

Replacement Considerations

Direct substitutes include other ISL32172E variants with different packages such as ISL32172EFBZ-T (SOIC-16). Cross-reference pinouts and electrical characteristics carefully before substitution.
