ICL3243ECAH-T

Drivers, Receivers, Transceivers Overview

The ICL3243ECAH-T is an RS-232 transceiver manufactured by Intersil, operating within a supply voltage range of 3 V to 5.5 V. It features three drivers and five receivers, supporting full-duplex communication at data rates up to 250 kb/s. The device incorporates enhanced automatic powerdown functionality, reducing the typical supply current to 1 mA during idle states. It provides 15 kV electrostatic discharge (ESD) protection on all RS-232 lines. The component is housed in a 28-pin SSOP package and is rated for commercial operation temperatures between 0°C and +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated enhanced automatic powerdown circuitry for reduced standby power consumption
