HIN202ACA

Overview

The HIN202ACA is a single-supply RS-232 transceiver manufactured by Harris Corporation, designed for EIA/TIA-232-F and V.28/V.24 compliance. It integrates onboard voltage converters to generate dual supplies from a single +5V source, eliminating the need for external negative rails. The device features two drivers and two receivers with TTL/CMOS-compatible inputs. Key electrical parameters include a data rate of 120 kbps, an operating supply voltage range of 4.5V to 5.5V, and a typical quiescent current of 15 mA. It operates within a temperature range of 0°C to +70°C and is housed in a 16-pin SSOP package.

Feature Summary

• Integrates charge pump circuitry to derive positive and negative voltages from a single +5V power supply.
• Provides full duplex communication capability with dedicated driver and receiver channels.
• Features input compatibility with standard TTL and CMOS logic families.

Applications

• Portable computers and laptop serial port implementations
• Industrial instrumentation requiring isolated serial communication
• Point-of-sale terminals and peripheral interconnects

Procurement Notes

Verify the manufacturer designation carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the component is sourced from authorized distributors holding valid Renesas inventory or verified surplus stock. Confirm the specific suffix 'ACA' corresponds to the commercial temperature grade and SSOP packaging variant to avoid substitution errors with other pinouts or speed ratings.

Selection Notes

Select this component when a system requires RS-232 connectivity but lacks a negative voltage rail. It is suitable for applications demanding moderate data rates up to 120 kbps. Designers must account for the external capacitors required for the internal charge pump. Compare against newer integrated solutions if lower power consumption or higher data throughput is required for the target application.

Part Context

The HIN202ACA belongs to the HIN202 series of line transceivers originally developed by Harris Semiconductor. This family was widely adopted in the 1990s and early 2000s for serial communication interfaces. Following corporate restructuring, the product line transitioned to Renesas Electronics. The part represents a legacy interface solution commonly found in existing industrial and consumer electronic designs.
