概述

Description

ICL3232IVZ is a dual RS-232 transceiver from Intersil (now Renesas). It provides two drivers and two receivers to link a microcontroller (TTL/CMOS) with RS-232 devices.
- Converts TTL/CMOS logic levels to RS-232 voltage levels (and vice versa).
- Operates from a single supply (typical 3–5.5 V) and uses an on-chip charge pump to generate RS-232 voltages.
- External capacitors are required for the charge pump (check the datasheet for values).
- Suitable for standard asynchronous serial interfaces and common data rates.
- IVZ denotes a specific package/grade; refer to the datasheet for exact pinout, voltage/current specs, and timing.
For precise specifications, consult the ICL3232IVZ datasheet.

Features

Key features of ICL3232IVZ (dual RS-232 transceiver):
- Dual channel: 2 drivers and 2 receivers
- Single-supply operation: 3.0 V to 5.5 V
- On-chip charge pump to generate RS-232 voltage levels from a single supply
- External capacitors required for the charge pump (typical small value)
- TTL/CMOS-compatible input thresholds; RS-232 voltage levels at outputs
- Suitable for standard UART speeds (hundreds of kbps range)
- Small IVZ (16-pin) package
- Features suitable for robust, low-power serial I/O without a ±12 V supply

Package

ICL3232IVZ comes in an 8-pin plastic DIP (PDIP) package.

Pinout

Pin count: 16 pins (DIP-16/SO-16).
Function: Dual RS-232 transmitter/receiver (two drivers and two receivers). Converts TTL/CMOS to RS-232 levels and back, using a charge-pump to generate the RS-232 voltage rails from a single supply. Pinout includes T1IN, T2IN, T1OUT, T2OUT, R1IN, R2IN, R1OUT, R2OUT, V+, V-, C1+/C1-, C2+/C2-, Vcc, and Gnd. External capacitors required for the charge pump.

Manufacturer

Manufacturer: Intersil (now part of Renesas Electronics).
What kind of company: A semiconductor company that designs and sells analog and mixed-signal integrated circuits (ICs) used in power management, communications, and interface devices.

Application

ICL3232IVZ is a dual RS-232 transceiver. Applications:
- Serial interfaces between MCUs/MPUs and RS-232 devices (PC COM ports, modems, printers)
- TTL/CMOS to RS-232 level shifting with integrated charge pump for ± voltages
- Space- and power-constrained embedded systems in industrial controls, data loggers, measurement equipment, POS terminals, and other serial communications gear.
