HIN213ECAZ-T

Overview

The HIN213ECAZ-T is a high-speed RS-232 transceiver from the HIN202E/HIN213E family, designed for single +5V operation without requiring ±12V supplies. It integrates onboard charge pumps to generate internal +10V and -10V rails using external 0.1µF capacitors. The device features four drivers and two receivers with ±15kV ESD protection on I/O pins. It supports data rates up to 230kb/s and includes a low-power shutdown mode; notably, the two receivers remain active during shutdown to enable system wakeup. It operates within a commercial temperature range of 0°C to +70°C in a 28-pin SSOP package.

Feature Summary

• Integrated charge pump voltage converters eliminate the need for external dual polarity power supplies.
• Low power shutdown mode conserves energy while maintaining receiver activity for system wake-up.
• Transmitter outputs and receiver inputs provide robust ±15kV electrostatic discharge protection.
• Redesigned transmitter circuitry ensures compatibility with ISDN and high-speed modem applications.

Applications

• ISDN terminal adaptors
• High-speed modems
• Portable computer peripheral interfaces

Procurement Notes

Verify the specific suffix 'CAZ' against manufacturer documentation to confirm lead-free status and RoHS compliance. Confirm that the '-T' suffix indicates tape-and-reel packaging rather than tube packaging. Ensure the selected variant matches the required commercial temperature range specifications for the target application environment.

Selection Notes

Select this component when designing systems limited to a single +5V supply rail. Choose this model over standard RS-232 transceivers if integrated charge pumps are required to reduce external component count. Consider this part specifically for battery-powered devices due to its shutdown capability and active receiver wake-up feature.

Part Context

This device belongs to the HIN202E through HIN232E family of RS-232 interface circuits. These components meet EIA high-speed RS-232E and V.28 specifications. The family provides various driver/receiver combinations, with the HIN213E specifically offering a 4-driver and 2-receiver configuration optimized for complex serial communication ports.

FAQ

How does the HIN213ECAZ-T handle system wake-up from shutdown?

Unlike other family members, the HIN213E keeps its two receivers active even when the device is in low-power shutdown mode, allowing it to detect incoming signals and trigger a system wake-up.

What external components are required for the charge pumps?

The device requires two external 0.1µF capacitors connected to the onboard charge pump voltage converters to generate the necessary positive and negative internal supply voltages.

Is the HIN213ECAZ-T compatible with TTL/CMOS logic levels?

Yes, the drivers feature true TTL/CMOS input compatibility, allowing direct interfacing with standard digital logic families without additional level shifting.
