ST232CTR

Product Overview

The ST232CTR from STMicroelectronics is a 16-TSSOP RS232 transceiver integrated circuit. It provides two drivers and two receivers with full-duplex operation, supporting serial data communication at 220Kbps. The device operates from a 4.5V to 5.5V supply and has a specified receiver hysteresis of 500 mV. Its 0°C to 70°C operating temperature range and 16-TSSOP package are relevant for board-level interface sections where RS232 signal conversion is required.

Key Features

• RS232 protocol transceiver with two drivers and two receivers
• Full-duplex communication path for simultaneous transmit and receive functions
• Supports a specified data rate of 220Kbps
• Provides 500 mV receiver hysteresis
• Operates from a 4.5V to 5.5V supply
• Rated for 0°C to 70°C operating temperature
• Uses a 16-TSSOP package

Applications

• Embedded systems requiring a 4.5V to 5.5V RS232 serial interface
• Equipment using two transmit and two receive channels for bidirectional serial data exchange
• Point-to-point RS232 links between board-level circuitry and external serial connectors

Design & Procurement Notes

When selecting the ST232CTR, confirm that the host system can provide a 4.5V to 5.5V supply and that the specified serial data rate is 220Kbps. The 2/2 full-duplex channel configuration supports two transmit and two receive paths, so board layout should accommodate both functions within the 16-TSSOP footprint. The 500 mV receiver hysteresis and 0°C to 70°C temperature range should be checked against expected signal margins and ambient conditions. Because the package is 16-TSSOP, assembly planning should account for the footprint. Use the exact manufacturer part number ST232CTR when specifying the RS232 transceiver variant.
