  • Product Introduction

Key features:

Fail-protected RS-485 bus pins: up to ±60V Extended common mode range: ± 20V RS-485 requirements are greater than Based on the RS-485 bus pin, it has ± 15kV HBM ESD protection Wide supply voltage range: 3V to 5.5V The cable reversal pin (ISL32457E only) corrects the reversal cable connection while maintaining full fail-safe function for receiving it 1/4 unit load on the bus for up to 128 devices High transient overvoltage tolerance: ±80V All fail-safe (open, short, terminated) RS-485 reception RS-485 data transfer rate: 250Kbps or 1Mbps choice Low quiescent current: 2.1 mA Ultra-low shutdown supply current: 10μA Lead-free (RoHS compliant) description

With ISL32457E, ISL32450E 3.3V to 5V power supply, fault protection, extended common-mode range differential transceiver, balanced communication. The overvoltage protected RS-485 bus pins (driver output and receiver input) ± 60V for ESD shock ± 15kV. The operating environment of these transceivers is characterized by common-mode voltages up to ±20V (exceeding RS-485 requirements), making this possible RS-485 Series 1, which is even stronger in the market. The transmitter is RS-485 compliant with V CC≥4.5V and CC=3V receiver (RX) inputs to RS-485 regulations, and even provides a "complete fail-safe" design with a V54Ω load providing a differential output voltage of 1 1.1V, thus guaranteeing a logic high Rx output if the Rx input floats, shorts or terminates, but is not driven (idle) on the bus. The ISL32457E conversion function that can maintain Rx input polarity switching (ISL32457E on the cable inversion function) when receiving full fail-safe operation includes cables, and in the case of Rx and Tx bus cables with reversing polarity, there is an error during installation, see Table 1 on page 2 for the main features and equipment number configuration.
