Intersil Corporation, in the design and manufacture of high-performance analog semiconductors, introduced the ISL317XE family of 3.3V RS-485/RS-422 transceivers. This nine-member family saves 50-70% of valuable board space and delivers the industry’s full-featured IEC61000 ESD-protected transceivers with 20Mbps data transmission rate.
Randy Pitts, marketing manager of Intersil’s Interface products group, said, “IEC61000 ESD protection on the I/O pins and 7kV HBM on all other pins in Intersil’s ISL317XE family provides a high degree of reliability in both manufacturing and end consumer applications and eliminates the need for external protection circuitry.”
The new devices come in space-saving MSOP (mini small-outline package) sizes that allow designs to drop old 8- and 14-lead SOIC transceivers. The 8-lead MSOP package provides a 50 percent board space savings over 8-lead SOIC packages and Intersil’s 10-lead MSOP package saves 70 percent over old 14-lead SOIC package options.
Pitts, added, “We believe the ongoing change from 5V to 3.3V supply voltages is permanent. Our board space advantage over our competitors will become more important as those changes continue throughout the industry.”
The ISL317XE family covers all features and configurations associated with the RS-485 protocol. Data rate options are offered to match the application speed. For low-speed applications, the family offers slew-rate-limited versions at 250kbps: ISL3170E/71E/72E, and 500kbps: ISL3173E/74E/75E. The ISL3176E/77E/78E operates up to 20Mbps for high-speed applications.
