HIN202IP

Overview

The HIN202IP is a dual RS-232 transmitter and receiver interface circuit manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing onboard charge pumps to generate the necessary positive and negative voltages for RS-232 signaling. The device complies with EIA high-speed RS-232E and V.28 specifications. It features TTL/CMOS input compatibility, slew-rate-limited outputs, and inputs protected against ±15kV electrostatic discharge (ESD). The receiver inputs tolerate up to ±30V and include hysteresis for improved noise rejection. The component is housed in a 28-pin Plastic Dual In-line Package (PDIP) suitable for through-hole mounting.

Feature Summary

• Single +5V power supply operation eliminates the need for external negative voltage sources.
• Integrated charge pump circuitry generates internal +10V and -10V supplies.
• Transmitter outputs and receiver inputs are protected against ±15kV electrostatic discharge.
• Receiver inputs feature hysteresis to enhance noise immunity in noisy environments.

Applications

• Portable computers and laptop peripheral connections
• Industrial instrumentation and control systems
• Uninterruptible Power Supply (UPS) communication ports

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas Electronics. Ensure the specific part number matches the required package style and temperature range. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Cross-reference datasheets from current authorized distributors to ensure the component meets current manufacturing standards.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with single-supply convenience. It is appropriate for designs where space constraints prevent external voltage inverters. Consider the PDIP package for prototyping or applications requiring through-hole technology. Verify that the data rate requirements align with the device's slew rate limitations compared to higher-speed alternatives in the family.

Part Context

The HIN202IP belongs to the HIN202E family of RS-232 transceivers designed for low-power, single-supply applications. This family includes variants with different numbers of drivers and receivers, such as the HIN203E and HIN204E. The 'IP' suffix typically denotes the PDIP package and commercial temperature range. These devices bridge the gap between TTL/CMOS logic levels and RS-232 voltage standards without complex external circuitry.

Replacement Considerations

Direct replacements include the HIN202ECN (SOIC package) or HIN202EPC (PLCC package) for pin-compatible form factors. Modern equivalents from Renesas or other manufacturers may offer updated packaging or enhanced ESD protection while maintaining functional compatibility.
