LAN8742A-CZ-TR

Product Overview

The LAN8742A-CZ-TR from Microchip Technology is a surface-mount transceiver intended for MII and RMII interface applications. It provides one driver and one receiver in full duplex operation and supports a data rate of 100Mbps. The device is supplied in a 24-SQFN (4x4) package with a 24-VFQFN exposed pad, and it operates from a 1.6V to 3.6V supply across an 0°C to 85°C temperature range. The transceiver provides transmission and reception functions for MII and RMII interfaces.

Design & Procurement Notes

When selecting this transceiver, confirm that the system interface uses MII or RMII signaling and that the supply remains within 1.6V to 3.6V. The 100Mbps data rate and full duplex configuration should match the required communication link. Board layout should account for the 4x4 mm surface-mount package and exposed pad, and the design should ensure operation stays within 0°C to 85°C. Because the package includes an exposed pad, thermal relief and solder land design should be reviewed before assembly. If the target environment falls outside the specified temperature range, this device should not be selected. For procurement, verify package orientation, solder land pattern, and thermal relief for the exposed pad, as these details affect assembly and reliability.
