HIN211CAZ-T

Overview

The HIN211CAZ-T is an RS-232 transceiver manufactured by Renesas Electronics. It integrates four drivers and five receivers, supporting full-duplex communication at data rates up to 230 kb/s. The device operates on a single +5V power supply (4.5V to 5.5V) with onboard charge pumps generating ±10V. It features ±15kV ESD protection on I/O pins, low power shutdown mode, and TTL/CMOS compatibility. The component is housed in a 28-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates need for external dual voltage supplies
• High electrostatic discharge protection on transmitter and receiver pins
• Low power shutdown capability for energy conservation
• TTL and CMOS input logic compatibility

Applications

• ISDN terminal adaptors
• High-speed modem interfaces
• Portable computer serial ports
• Industrial instrumentation systems

Procurement Notes

Verify the suffix 'CAZ' against official Renesas documentation to confirm specific package variant and RoHS compliance status. Ensure the '-T' designation matches the required reel or cut tape packaging format for your assembly line. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current product availability and authenticity before procurement.

Selection Notes

Select this component when designing systems requiring multiple transmit and receive channels without access to ±12V power rails. The high ESD rating makes it suitable for environments prone to static discharge. Verify that the 230 kb/s data rate meets application requirements and that the 28-pin SSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the HIN211E family of RS-232 transmitters and receivers. The family shares common specifications regarding the single +5V operation and onboard voltage conversion. Variations within the family typically involve differences in driver/receiver counts or specific package options, while maintaining core interface functionality.

Replacement Considerations

Compatible substitutes include other members of the HIN211 series such as HIN211E or HIN211IA. These parts share similar electrical characteristics and pinouts but may differ in temperature ranges or package styles. Verify functional equivalence before substitution.
