HIN237ACB-T

Overview

The HIN237ACB-T is a single-function RS-232 line transceiver manufactured by Harris Corporation. It integrates two drivers and two receivers within a CMOS technology platform, housed in a 16-pin PDSO package. The device complies with EIA-232-E, V.24, and V.28 interface standards. It operates within a temperature range of -40°C to +70°C. Key electrical parameters include a maximum high-level input current of 0.00004 A, a minimum output swing of 10 V, and a maximum low-level output current of 0.0032 A. The inputs utilize Schmitt trigger characteristics for noise immunity, while the outputs provide inverted polarity.

Feature Summary

• Integrates dual driver and dual receiver channels for bidirectional serial communication
• Features Schmitt trigger inputs to enhance noise rejection capabilities
• Includes onboard charge pump circuitry to generate required voltage levels from a single supply
• Provides TTL/CMOS compatible input logic levels

Applications

• RS-232 serial port implementations in industrial control systems
• Data communication interfaces for embedded computing devices
• Modem and peripheral connectivity solutions
• Terminal equipment requiring standard serial signaling

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as original specifications indicate non-compliance; check for updated lead-free variants if environmental regulations require. Validate package marking and date codes against official shipping documents to ensure traceability and prevent counterfeit infiltration.

Selection Notes

Select this component when designing systems requiring standard RS-232 signaling with integrated voltage generation. Ensure the application supports the specific 16-pin PDSO footprint. Verify that the single-supply architecture aligns with the system power budget. Consider thermal performance within the specified operating temperature range during layout planning.

Part Context

This part belongs to the HIN23x family of RS-232 transceivers designed for single-supply operation. It shares functional similarities with other members like the HIN232 and HIN209 but offers specific driver/receiver counts suited for standard duplex communication needs. The series emphasizes simplified design by eliminating the need for external negative voltage supplies.

Replacement Considerations

Consider the HIN232ACA or HIN232ACB-T for equivalent functionality within the same product family. Verify pinout compatibility and electrical specifications before substitution. Check for availability of lead-free versions if regulatory compliance is mandatory.
