TIOL1123LYAHR

Drivers, Receivers, Transceivers Overview

The TIOL1123LYAHR is an IO-Link device transceiver from Texas Instruments, housed in a 12-pin DSBGA package measuring 2.45 mm by 1.70 mm. It operates on a supply voltage range of 7 V to 36 V with a quiescent current of 1.5 mA typical. The device features an integrated linear regulator providing a selectable 3.3-V or 5-V output at up to 20 mA. It supports IEC 61131-9 COM1, COM2, and COM3 data rates and includes active reverse polarity protection up to 65 V. Integrated EMC protection handles ±8 kV ESD contact discharge, ±4 kV EFT, and ±1.2 kV surge. The operating temperature range extends from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Configurable LDO output allows selection between 3.3 V and 5 V logic supplies via the VSEL pin.
• Integrated surge and transient protection ensures robustness against industrial electrical noise.
• Active driver current limiting protects loads while allowing wake-up pulse generation for master applications.

Drivers, Receivers, Transceivers Applications

• IO-Link PHY implementation in remote I/O systems
• Industrial field transmitters and actuators
• Factory automation control nodes

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix LYAHR corresponds to the DSBGA package and selectable LDO configuration. Confirm that the component meets RoHS standards and humidity sensitivity levels required for the intended manufacturing process. Ensure the supplier provides valid traceability documentation for production batches.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a compact DSBGA footprint is required alongside a programmable logic supply voltage. It serves as a direct upgrade to the TIOL111 series with improved thermal performance and lower residual voltage. Consider the VSEL pin requirement for setting the LDO output level during PCB layout.

Drivers, Receivers, Transceivers Part Context

This component belongs to the TIOL112x family of IO-Link transceivers designed for industrial sensor interfaces. It maintains pin compatibility with the previous TIOL111 series in other packages but offers enhanced electrical characteristics. The family supports both standard IO-Link communication and SIO modes for flexible system integration.

Drivers, Receivers, Transceivers Replacement Considerations

The TIOL1123DRCR is a pin-compatible alternative using a VSON-10 package. Verify that the larger package size fits the design constraints if substituting. Both devices share similar electrical specifications and functional capabilities within the TIOL112x family.
