HIN237ECP

Overview

The HIN237ECP is a dual RS-232 transceiver manufactured by Harris Corporation, operating from a single +5 V power supply. It integrates charge pumps to generate the required positive and negative voltages for RS-232 signal levels without external components. The device features low supply current consumption and includes receiver input hysteresis to filter noise. It supports data rates up to 120 kbps and operates within a temperature range of -40 °C to +85 °C. The component is housed in a 16-pin plastic DIP package.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external capacitors or split power supplies.
• Provides full RS-232 compliance with internal voltage generation for transmit and receive drivers.
• Includes receiver input hysteresis to improve noise immunity on serial communication lines.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Embedded computer systems utilizing RS-232 for peripheral connectivity.
• Test and measurement equipment needing isolated serial data transmission.

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successor entities, noting that acquisition history may affect part marking. Confirm the package type matches the 16-pin DIP specification. Ensure the temperature grade corresponds to the industrial range requirements for the intended deployment environment.

Selection Notes

Select this component when a single +5 V supply is available and external charge pump capacitors must be avoided to save board space. Compare against modern equivalents if higher data rates or lower power consumption are critical. Verify pin compatibility with existing designs if substituting similar dual transceivers.

Part Context

This device belongs to the family of RS-232 interface transceivers designed for microprocessor-based systems. It serves as a level converter between TTL/CMOS logic levels and standard RS-232 voltage swings. Its design focuses on simplifying circuit layout by integrating the necessary voltage inversion and multiplication functions internally.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate generic dual RS-232 transceivers with identical pinouts and electrical specifications for potential cross-referencing.
