Detailed Description for ST232BDR
Product Overview
The ST232BDR from STMicroelectronics is a surface-mount RS232 transceiver intended for serial data interfaces that require two drivers and two receivers in a full-duplex arrangement. The device operates from a 4.5 V to 5.5 V supply and supports a data rate of 220 Kbps, with a specified receiver hysteresis of 500 mV. It is offered in a 16-SOIC package with a 0.154 in body width for surface-mount layouts that require RS232 signal conversion within the specified temperature range.
Key Features
- Full-duplex RS232 transceiver architecture with 2 drivers and 2 receivers for simultaneous transmit and receive operation.
- Supports a data rate of 220 Kbps, with a receiver hysteresis specification of 500 mV.
- Operates from a 4.5 V to 5.5 V supply.
- Specified operating temperature range is -40°C to 85°C.
- Surface-mount 16-SOIC package with 0.154 in (3.90 mm) width.
Applications
- RS232 serial links between microcontroller-based boards and host computers.
- Serial configuration, diagnostic, or data transfer ports on embedded control equipment.
- Point-to-point serial communication channels in instruments, gateways, or adapter interfaces.
Design & Procurement Notes
The ST232BDR should be selected when a board requires a full-duplex RS232 transceiver with two transmit and two receive channels in a 16-SOIC footprint. Layout should account for the surface-mount package and the 0.154 in body width. Power supply design should keep the device within its 4.5 V to 5.5 V operating range, and system data rate should not exceed the specified 220 Kbps. The 500 mV receiver hysteresis can be considered when evaluating input signal transitions, while the -40°C to 85°C temperature range should be checked against the intended operating environment. Exact part number ST232BDR should be specified to ensure the correct package and device are procured.
