DATASHEET
±16.5kV ESD Protected, 16Mbps, with Active Low Rx EN, RS-485/422 Receiver
ISL3282EMRTEP
The Intersil ISL3282EMRTEP is a ±16.5kV IEC61000 ESD protected, 3.0V to 5.5V powered, single receiver that meets both the RS-485 and RS-422 standards for balanced communication. This receiver has very low bus currents (+125µA/-100µA), so it presents a true “1/8 unit load” to the RS-485 bus. This allows up to 256 receivers on the network without violating the RS-485 specification’s 32 unit load maximum and without using repeaters.
Receiver inputs feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven.
The ISL3282EMRTEP includes an active low enable pin and is offered in the Military Temperature range (-55°C to +125°C).
A 26% smaller footprint is available with the TDFN package. This device also features a logic supply pin (VL) that sets the VOH level of the RO output (and the switching points o...
