ISL3298EMRTEP - Low Power RS-485/RS-422 Transmitter

General Description

VL Logic-Level supply which sets the VIL/VIH levels for the DI and DE pins.

Power-up this supply after VCC, and keep VL ≤VCC.

DE Driver output enable.

Key Features

  • Specifications per DLA VID V62/10602.
  • Full mil-temp electrical performance from -55°C to +125°C.
  • Controlled baseline with one wafer fabrication site and one assembly/test site.
  • Full homogeneous lot processing in wafer fab.
  • No combination of wafer fabrication lots in assembly.
  • Full traceability through assembly and test by date/trace code assignment.
  • Enhanced process change notification.
  • Enhanced obsolescence management.

DATASHEET ISL3298EMRTEP 16kV ESD Protected, +125°C, 3.0V to 5.5V, TDFN Packaged, Low Power RS-485/RS-422 Transmitter FN7607 Rev.2.00 Oct 24, 2019 The ISL3298EMRTEP is a ±16.5kV HBM ESD Protected (7kV IEC61000 contact), 3.0V to 5.5V powered, single transmitter for balanced communication using the RS-485 and RS-422 standards. This driver has very low bus currents (±40mA); therefore, it presents 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 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.
