ISL3295E Datasheet Rs-485/rs-422 Transmitters

Manufacturer: Renesas

Overview: DATASHEET ISL3295E, ISL3298E ±16.5kV ESD Protected, +125°C, 3.0V to 5.5V, SOT-23/TDFN Packaged, Low Power, RS-485/RS-422 Transmitters FN6544 Rev.4.00 Oct 9, 2019 The ISL3295E and ISL3298E are ±16.5kV HBM ESD Protected (7kV IEC61000 contact), 3.0V to 5.5V powered, single transmitters for balanced communication using the RS-485 and RS-422 standards. These drivers have very low output leakage current (±40µA), so they present less than a “1/8 unit load” to the RS-485 bus. This allows more than 256 transmitters on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters. Hot Plug circuitry ensures that the Tx outputs remain in a high impedance state while the power supply stabilizes. Drivers on the ISL3295E and ISL3298E are not limited, so they can achieve the 20Mbps data rate. They are offered in industrial and extended industrial (-40°C to +125°C) temperature ranges. A 26% smaller footprint is available with the ISL3298E TDFN package.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key Features

  • a logic supply pin (VL) that sets the switching points of the DE and DI inputs to be compatible with a lower supply voltage in mixed voltage systems. For companion single RS-485 receivers in micro packages, please see the ISL3280E, ISL3281E, ISL3282E, ISL3283E, ISL3284E datasheet.
