HIN211CB

Overview

The HIN211CB is a quad line transceiver from the HIN200-HIN213 family, designed for RS-232 communications. It meets EIA RS-232E and V.28 specifications using a single +5V power supply. Onboard charge pumps generate ±10V supplies from the 5V input, requiring only 0.1µF external capacitors. The device features four drivers with 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. Data rates reach 120kbit/s. Typical low power consumption is 5mA, with a shutdown mode reducing current to 1µA.

Feature Summary

• Onboard voltage conversion generating ±10V from a single +5V supply
• Low power shutdown function for energy conservation in battery applications
• TTL/CMOS compatible inputs with three-state receiver outputs
• High noise rejection through receiver hysteresis

Applications

• Computer serial ports
• Portable and laptop systems
• Peripheral connections such as printers and terminals
• Instrumentation equipment
• Modem interfaces

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation assets were acquired by Renesas Electronics. Confirm the specific suffix (e.g., CBZ) indicates RoHS compliance and lead-free status. Ensure the package type matches the required board layout, typically SSOP-28 or PDSO-28. Check for availability of original Harris versus Renesas branded units if historical consistency is critical.

Selection Notes

Select this component when ±12V supplies are unavailable and a single +5V rail must drive RS-232 signals. It is suitable for space-constrained designs due to minimal external capacitor requirements. Consider the HIN213 variant if active receivers in shutdown mode are needed for wakeup functionality. Verify data rate requirements against the 120kbit/s limit.

Part Context

This part belongs to the HIN200-HIN213 family of +5V powered RS-232 transmitters and receivers. Originally developed by Harris Semiconductor, the product line was transferred to Intersil and subsequently to Renesas Electronics. The family provides various driver/receiver combinations to accommodate different interface needs while maintaining standard RS-232 electrical characteristics.

Replacement Considerations

Public confirmed substitutes include the HIN211CBZ-T manufactured by Renesas Technology Corp. Other family members like HIN206 or HIN213 may serve similar roles but differ in driver/receiver counts or shutdown features.
