HIN202IA

Overview

The HIN202IA is a dual RS-232 transmitter and receiver manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing onboard charge pumps to generate the required positive and negative voltages for RS-232 signaling. The device supports data rates up to 120 kbit/s and features two drivers and two receivers. It meets EIA RS-232E and V.28 specifications, providing TTL/CMOS compatible inputs and outputs with low power consumption characteristics suitable for various communication interfaces.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external ±12V supplies
• TTL and CMOS input/output compatibility ensures broad digital interface integration
• Low power shutdown mode significantly reduces standby current consumption

Applications

• Portable computers and laptop serial ports
• Mainframe computer peripheral connections
• Printers and terminal devices requiring RS-232 links

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Intersil, which later became part of Renesas Electronics. Ensure the specific suffix 'IA' matches the required temperature range and package variant for your design. Cross-reference datasheets from all relevant entities to confirm pinout consistency and electrical parameters before finalizing procurement.

Selection Notes

Select this component when designing systems limited to a single +5V power rail without access to higher voltage rails. It is appropriate for applications requiring moderate data speeds up to 120 kbit/s. Consider the HIN203 or HIN205 if minimizing external capacitor count is a priority, or other family members like the HIN232 if different driver/receiver configurations are needed.

Part Context

This device belongs to the HIN200-HIN213 family of RS-232 transceivers designed for single-supply operation. The family provides various combinations of drivers and receivers to suit different interface requirements while maintaining compliance with standard RS-232 protocols. This specific model offers a balanced configuration for general-purpose serial communication tasks.
