HIN236ACP

Overview

The HIN236ACP is a dual RS-232 driver and receiver transceiver manufactured by Harris Corporation. It operates from a single +5V power supply and incorporates a charge pump circuit to generate the necessary positive and negative voltages for EIA/TIA-232-F signal levels. The device features low supply current consumption and supports data rates up to 120 kbps. It includes internal discharge protection on the driver outputs to prevent voltage spikes during power-up or power-down conditions, ensuring robust performance in industrial communication environments.

Feature Summary

• Integrated charge pump eliminates the need for external bipolar power supplies
• Internal output discharge protection safeguards against transient voltage events
• Single +5V operation simplifies power design requirements

Applications

• Industrial serial communication interfaces
• Modem connections
• Point-of-sale (POS) systems
• Medical equipment serial ports

Procurement Notes

Verify the package type matches the required PCB footprint, as the ACP suffix typically denotes a specific surface-mount or through-hole configuration. Confirm that the manufacturer source is authorized to ensure component authenticity and traceability. Check for any lead-free compliance markings if environmental regulations apply to the final assembly.

Selection Notes

Select this component when designing systems requiring dual independent RS-232 channels with minimal external passive components. It is suitable for applications where space constraints prohibit bulky external charge pumps or dual-voltage regulators. Ensure the operating temperature range meets the environmental specifications of the target deployment area.

Part Context

Harris Corporation was a prominent defense and communications electronics manufacturer before its acquisition by L3Harris Technologies. The HIN series represents legacy interface components originally developed for reliable serial data transmission. These parts remain relevant in maintenance and retrofit scenarios for existing industrial infrastructure built during the era of standard RS-232 dominance.

Replacement Considerations

Direct pin-compatible replacements include the MAX232ACPE and the SP232EEN. Verify that substitute devices maintain the same voltage tolerance and drive strength characteristics to ensure signal integrity without modifying the surrounding circuitry.
