RS-485/RS-422 single transmitter provides 16.5-kV ESD protection

Milpitas, Calif.—Intersil Corp. announced the ISL329xE series of 3.3V-powered RS-485/RS-422 single transmitters designed with ±16.5-kV ESD protection and ultra-low supply current requirement.

The ISL329xE devices come in very small TDFN and SOT23 packages, both of which are available in the industrial and extended industrial (-40°C to +125°C) temperature ranges.

The ISL329xE single transmitter family offers data rate options to match the application speed. For low-speed applications, the family offers slew rate-limited versions at 250-kbits/s (ISL3293E and ISL3296E), as well as 500-kbits/s versions (ISL3294E and ISL3297E). The ISL3295E and ISL3298E operate up to 20-Mbits/s for high-speed applications.

This family of transmitters has low quiescent supply current (Icc = 150 microamps max). All the devices feature a Tx enable pin that places the IC in a low power shutdown mode (Icc = 1 microamps max) to further reduce power consumption whenever the transmitter is disabled.

The ISL3296E, ISL3297E and ISL3298E are all available in 8-lead TDFN packaging (2mm x 3mm), making them 26% smaller than SOT23 package options (3mm x 3mm), according to Intersil. These versions feature on-board level translators on the enable and data input pins that simplify the design of mixed voltage systems. The logic supply pin (VL) can be connected to a lower voltage processor supply to level shift the input voltages to values compatible with the processor supply. This eliminates the need for external level translators.

Pricing: In 1,000-unit quantities, the devices cost $1.20 for the extended industrial temperature grade and $0.87 for industrial temperature grade.
