ISL3280E
ISL3280E is RS-485/RS-422 Receivers manufactured by Renesas.
feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven.
The ISL3280E and ISL3284E feature an always enabled Rx; the ISL3281E features an active high Rx enable pin and the ISL3282E and ISL3283E include an active low enable pin. All versions are offered in Industrial and Extended Industrial (-40°C to +125°C) temperature ranges.
A 26% smaller footprint is available with the ISL3282E TDFN package. These devices, plus the ISL3284E, also feature a logic supply pin (VL) that sets the VOH level of the RO output (and the switching points of the RE/RE input) to be patible with another supply voltage in mixed voltage systems.
For panion single RS-485 transmitters in micro packages, see the ISL3295E, ISL3298E datasheet.
