Intersil Corporation’s ISL329xE series of 3.3V-powered RS-485/RS-422 single transmitters are designed with excellent +/-16.5kV ESD protection and ultra-low supply current requirement. These devices come in small TDFN and SOT23 packages with both package types available in the industrial and extended industrial (-40C to +125C) temperature ranges.
This single transmitter family offers data rate options to match the application speed. For low-speed applications, the family offers slew rate-limited versions at 250kbps (ISL3293E and ISL3296E), as well as 500kbps versions (ISL3294E and ISL3297E). The ISL3295E and ISL3298E operate up to 20Mbps for high-speed applications.
This family of transmitters has low quiescent supply current (Icc = 150 microamps max) that is 1/30th the value of the nearest competitor, making a significant improvement in power critical applications. Additionally, 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.
