RENICL3243EIVZ-T
Overview
The ICL3243EIVZ-T is a low-power, 3-driver and 5-receiver RS-232 transceiver designed for battery-powered systems and portable instrumentation. It operates from a single 3V to 5.5V supply and features an automatic power-down mode that reduces supply current to 1uA when the serial port is inactive. The device includes integrated ESD protection up to 15kV (IEC61000) on all RS-232 I/O pins, eliminating the need for external protection components in most designs.
Why Choose This Part
This transceiver offers superior 15kV ESD protection and a high 500mV receiver hysteresis for excellent noise immunity in noisy industrial environments. Its 250kbps data rate and low 0.3mA operating current make it an efficient choice for modern 3.3V microcontrollers that need to interface with legacy serial peripherals.
Applications
Key Specifications
Getting Started
To implement this device, place four 0.1uF charge pump capacitors as close to the 28-TSSOP package as possible to ensure stable voltage doubling and inversion. For software control, the FORCEON and FORCEOFF pins allow the host MCU to manually override the automatic power-down logic when necessary. Ensure the supply voltage is decoupled with a 0.1uF ceramic capacitor.
