HIN233CP

Overview

The HIN233CP is a line transceiver manufactured by Harris Corporation, designed for RS-232 communication interfaces. It integrates two drivers and two receivers within a single CMOS package. The device operates on a single 5 V power supply and supports data rates up to 120 kbps. It utilizes external capacitors for charge pump voltage generation, eliminating the need for dual polarity supplies. The component is housed in a 16-pin PDIP package and is compatible with standard EIA-232-E, V.24, and V.28 interface standards.

Feature Summary

• Integrates dual drivers and dual receivers for bidirectional serial communication
• Operates from a single 5 V power supply using internal charge pumps
• Provides protection against electrostatic discharge and output short circuits

Applications

• Industrial control systems requiring RS-232 connectivity
• Modem interface circuits
• Point-of-sale terminals and barcode scanners

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successor entities like Intersil, given corporate acquisitions. Confirm the package type matches the required 16-pin DIP footprint. Check for compliance certifications if the application requires specific regulatory standards. Ensure the operating temperature range meets the environmental requirements of the target system.

Selection Notes

Select this component when a dual-channel RS-232 transceiver is needed with low power consumption. It is suitable for designs constrained by space due to its integrated charge pump. Compare pin compatibility with other HIN23x series devices if alternative sourcing is necessary. Verify that the 120 kbps speed is sufficient for the intended application bandwidth.

Part Context

This part belongs to the HIN232/HIN233 family of RS-232 transceivers. These components are widely used in legacy and industrial electronics for serial data transmission. The HIN233 variant specifically offers two transmit and receive channels, distinguishing it from single-channel counterparts like the HIN232.

FAQ

Does the HIN233CP require negative voltage supplies?

No, it uses an internal charge pump to generate negative voltages from a single 5 V positive supply.

What is the maximum data rate supported?

The device supports data rates up to 120 kbps.
