Description

ICL3232EIAZ-T is a dual RS-232 transceiver (two drivers and two receivers) from Intersil (Renesas). It converts TTL/CMOS logic levels to RS-232 levels and vice versa, using an on-chip charge-pump to generate the RS-232 voltages from a single supply (typically 3.3–5 V). It’s designed for microcontroller UART interfaces to connect to RS-232 devices (PCs, modems, etc.). The device is offered in a 16-pin (EIAZ) package with standard UART data rates, low power, and protection features; external capacitors are required for the charge pump. For exact voltage ranges, capacitor values, pinout, temperature range, and packaging options, consult the official datasheet.

Features

ICL3232EIAZ-T features (concise):
- Dual RS-232 transceiver: 2 drivers and 2 receivers (two TX/RX channels)
- Single-supply operation at 3.3 V (typical); supply range ~3.0–3.6 V
- Internal charge-pump to generate RS-232 levels from the 3.3 V supply
- Requires external charge-pump capacitors (C1–C4) for the pump
- Data rate up to about 250 kbps
- True RS-232 signaling with ± voltages suitable for standard interfaces
- TTL/CMOS-compatible input thresholds
- 8-pin package; Tape & Reel variant noted by -T
- Low power consumption
- Built-in protection (ESD) and robust operation over typical industrial temp range
Applications: microcontroller-to-PC/printer interfaces, USB-to-serial bridges, embedded serial links.

Package

It uses a 16-pin surface-mount SOIC package (SOIC-16) and is supplied in Tape‑and‑Reel packaging.

Pinout

- Pin count: 16 pins (DIP-16/SO-16 common package).
- Function: Dual RS-232 transceiver (two drivers and two receivers). Converts TTL/CMOS inputs (TIN) to RS-232 outputs (TOUT) and RS-232 inputs (RIN) to TTL/CMOS outputs (ROUT). Includes an internal charge-pump to generate RS-232 voltage levels; operates from 3.0–5.5 V and uses external pump capacitors.

Manufacturer

Manufacturer: Renesas Electronics Corporation (Intersil brand/origin).
Kind of company: a Japanese multinational semiconductor company that designs and manufactures integrated circuits (analog, power, MCU/embedded, etc.).

Application

ICL3232EIAZ-T is a dual RS-232 transceiver (two drivers, two receivers) with onboard charge pumps, for converting TTL/CMOS to RS-232 levels. Applications: connecting microcontrollers/UARTs to RS-232 devices; serial interfaces in embedded systems; PCs/modems/printers and other RS-232 peripherals; industrial control, instrumentation, data logging; and POS or telecom/network gear needing RS-232 links from a 3–5V supply.
