HIN207CP

Overview

The HIN207CP is a +5V powered RS-232 transmitter/receiver from the HIN200-HIN213 family, designed for applications lacking ±12V supplies. It features onboard charge pump voltage converters generating +10V and -10V from a single +5V source. The device includes two transmitters and two receivers, meeting EIA RS-232E and V.28 specifications. It supports data rates up to 120kbit/s with true TTL/CMOS input compatibility. The package is a 16-pin PDIP.

Feature Summary

• Onboard charge pump generates required RS-232 voltages from a single +5V supply
• Low power shutdown mode available for energy conservation in battery applications
• Drivers feature slew rate limiting and 300Ω power-off source impedance
• Receivers include hysteresis for improved noise rejection

Applications

• Portable computer serial ports
• Laptop peripheral connections
• Printers and terminals
• Instrumentation systems
• Modems and ISDN terminal adaptors

Procurement Notes

Verify the manufacturer origin as Harris Corporation or Intersil, noting that Intersil acquired Harris Semiconductor. Confirm the specific suffix 'CP' corresponds to the commercial temperature range (0°C to +70°C) and PDIP package. Ensure the datasheet matches the HIN207 variant with two drivers and two receivers before procurement.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 levels are required. The HIN207CP provides two channels, suitable for dual-port designs. Compare against the HIN207E if higher speed or ESD protection is needed. Verify board space constraints, as external capacitors are required for the charge pump circuit.

Part Context

This part belongs to the HIN200-HIN213 family of low-power RS-232 interface circuits. These devices were originally developed by Harris Semiconductor and later continued by Intersil after acquisition. The family allows designers to replace traditional dual-supply RS-232 solutions with simpler single-supply architectures.

Replacement Considerations

Public confirmed substitutes include the HIN207CPZ (Intersil version) and the MAX207CPE (Maxim Integrated). Verify pinout compatibility and electrical parameters such as data rate and operating temperature range before substitution.
