Descripción general

Description

MAX3243ECAI is Maxim’s quad RS-232 transceiver. It provides two RS-232 drivers and two RS-232 receivers, letting two UARTs talk to RS-232 devices. The device translates TTL/CMOS logic levels to RS-232 voltage levels (and back) from a single supply (typically 3.0–5.5 V) and uses an external charge-pump capacitor network to generate the RS-232 voltages (about ±6 V). It supports UART data rates up to roughly 1 Mbps per channel and is designed for low power operation. External capacitors (often 0.1 μF) are required for the charge pump. Applications include microcontroller UART interfaces to PCs, modems, and serial peripherals. The “ECAI” suffix denotes the device’s packaging and temperature grade (industrial/commercial variants) in the available package options.

Features

MAX3243ECAI is a quad RS-232 transceiver. Key features:
- 4 drivers + 4 receivers (quad RS-232 transceiver)
- Single-supply operation: 3.0V to 5.5V
- External charge-pump capacitors (typical four 0.1 µF) for RS-232 voltage generation
- TTL/CMOS-compatible input thresholds; RS-232-level outputs
- Supports standard RS-232 data rates (up to about 1 Mbps range, depending on conditions)
- ESD and short-circuit protection on I/O lines
- Suitable for commercial/industrial temperature ranges (as packaged in CAI)
Note: exact voltage swing, current, and speed specs depend on the specific device revision and conditions; consult the datasheet for precise values.

Package

16-pin TSSOP (SSOP) package.

Pinout

- Pin count: 28 pins (28-pin package, e.g., TQFP/SSOP)
- Function: Quad RS-232 transceiver (four drivers and four receivers) that interfaces between TTL/CMOS logic (TIN/RIN/ROUT/TOUT) and RS-232 signals. Uses an internal charge pump with external capacitors to generate the ± voltages; operates from 3.0–5.5 V.

Manufacturer
