HIN207CA-T

Overview

The HIN207CA-T is a +5V powered RS-232 transmitter/receiver manufactured by Harris Corporation. It meets EIA RS-232E and V.28 specifications, utilizing onboard charge pump voltage converters to generate +10V and -10V supplies from a single +5V power source. The device features true TTL/CMOS input compatibility, slew rate-limited outputs, and 300Ω power-off source impedance. Receivers handle up to ±30V inputs with hysteresis for noise rejection. This specific variant requires external capacitors of 0.1µF or greater.

Feature Summary

• Onboard voltage conversion generating dual supply rails from a single +5V source
• TTL and CMOS compatible logic inputs
• High noise immunity through receiver hysteresis
• Slew rate limited output drivers

Applications

• Serial communication interfaces in systems lacking ±12V power supplies
• Battery-powered equipment requiring low standby current
• Industrial control systems needing robust noise rejection

Procurement Notes

Verify the exact suffix 'CA-T' against official Harris documentation to confirm temperature range and tape-and-reel packaging status. Ensure the datasheet specifies the required external capacitor values for the charge pump circuit. Confirm RoHS compliance status as historical Harris data may vary.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required. Compare against the HIN203 or HIN205 if board space is critical, as those variants do not require external capacitors. Verify that the 120kbit/s data rate meets system requirements.

Part Context

The HIN207 is part of the HIN200-HIN213 family of RS-232 transceivers designed for +5V operation. This family eliminates the need for traditional dual-polarity power supplies by integrating charge pumps. The HIN207 specifically includes one driver and one receiver.
