AS2702-16T

Specialized Overview

The AS2702-16T is an AS-Interface slave IC in a SOIC 16W package, designed for serial bidirectional data communication and power extraction from the unshielded 2-wire bus. It supports up to 62 slave modules using extended addressing. The device interfaces up to 3 actuators or sensors via a 4-bit data port. It extracts nominal 30V DC bus voltage internally, regulating it to 5V for circuitry and 24V (max 35mA) for peripherals. Operating temperature ranges from -25°C to +85°C with typical supply current ≤6mA.

Specialized Feature Summary

• Interfaces actuators and sensors to AS-Interface bus systems
• Extracts DC power directly from the bus line
• Includes integrated 16x8 bit EEPROM for address storage
• Features LED outputs for status indication

Specialized Applications

• Industrial automation sensor integration
• Actuator control in AS-Interface networks
• Slave module connection to central master units

Specialized Procurement Notes

Verify the specific ordering suffix 'T' corresponds to tape and reel packaging as documented. Confirm the SOIC 16W package variant lacks the parameter port functionality available in the SOIC 20 version. Ensure compatibility with existing AS-Interface master controllers supporting the SAP4.1 specification.

Specialized Selection Notes

Select this model when the parameter port is unnecessary to minimize pin count. Verify that the application requires support for up to 62 slaves on the bus. Check if the operating temperature range of -25°C to +85°C meets environmental requirements. Confirm peripheral load does not exceed the 35mA limit at 24V.

Specialized Part Context

This component belongs to the AS2702 series of AS-Interface slave devices. It serves as a successor to the AS2701A, maintaining system compatibility while expanding addressable capacity. The SOIC 16W variant specifically omits the parameter port pins found in the full-function SOIC 20 version.

Specialized Replacement Considerations

AS2702-16: Identical electrical characteristics but supplied in tubes instead of tape and reel. AS2702-20T: Includes the parameter port functionality; verify if additional pins are required. AS2701A: Compatible predecessor but limited to 31 slaves without extended addressing.
