HIN202CP

Overview

The Intersil HIN202CP is a dual transmitter and receiver RS-232 interface circuit designed for full-duplex communication. It operates on a single +5V power supply, utilizing onboard charge pumps to generate the necessary positive and negative voltages for RS-232 signaling without requiring external ±12V sources. The device supports data rates up to 230 kbps and features 16-pin PDIP packaging. Key electrical parameters include a supply voltage range of 4.5V to 5.5V, an operating temperature range of 0°C to +70°C, and ±15kV ESD protection on I/O pins.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external dual-polarity power supplies
• High-speed transmitter circuit design suitable for ISDN and high-speed modem applications
• Integrated ±15kV electrostatic discharge protection on transmitter outputs and receiver inputs
• TTL/CMOS compatible inputs with slew-rate-limited outputs to minimize electromagnetic interference

Applications

• Portable computers and laptop systems requiring serial connectivity
• Industrial instrumentation and UPS systems
• Printers and terminals connected via RS-232 ports
• ISDN terminal adaptors and high-speed modems

Procurement Notes

Verify the specific suffix 'CP' indicates the PDIP package variant when sourcing. Confirm RoHS compliance status as older Intersil batches may differ from current Renesas specifications. Check for obsolescence notices since the component has been part of long-standing families. Ensure the supplier provides original manufacturer documentation rather than generic datasheets. Validate that the received units match the 16-pin through-hole configuration required for the target PCB layout.

Selection Notes

Select this component when a single +5V supply is available but RS-232 levels are required. Compare against HIN202ECBZ for surface-mount alternatives if space constraints exist. Consider the HIN213E if low-power shutdown modes are necessary for battery-operated devices. Verify that the 230 kbps speed meets the application requirements compared to standard 120 kbps variants. Ensure the 16-pin DIP footprint matches the existing board design before ordering.

Part Context

The HIN202CP belongs to the broader HIN202E/HIN232E family of RS-232 transceivers developed by Intersil, now part of Renesas Electronics. This family was engineered to simplify RS-232 interface design by removing the complexity of generating internal negative voltages. The CP suffix specifically denotes the plastic dual in-line package, distinguishing it from SOIC or TSSOP variants within the same functional family.

FAQ

Does the HIN202CP require external capacitors for its internal voltage generators?

Yes, the device requires external capacitors (typically 0.1µF) connected to the onboard charge pump pins to generate the +10V and -10V supplies needed for RS-232 operation.

What is the maximum data rate supported by the HIN202CP?

The HIN202CP supports data rates up to 230 kbps, making it suitable for high-speed applications such as ISDN and fast modems.

Is the HIN202CP compatible with TTL logic levels?

Yes, the transmitter inputs are true TTL/CMOS compatible, allowing direct interfacing with standard digital logic circuits without additional level shifting.
