Buffers, Drivers, Receivers, Transceivers Overview

The SN74AXC2T45DTMR is a dual-bit, dual-supply bus transceiver from the Texas Instruments SN74AXC2T45 series. It operates with supply voltages ranging from 0.65 V to 3.6 V on both ports and features an X2SON-8 package. The device provides a propagation delay of 4 ns and supports data rates up to 1 Gbps. It functions within an operating temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports voltage translation between independent power domains ranging from 0.65 V to 3.6 V
• Provides high-speed bidirectional data transfer with low propagation delay
• Designed for asynchronous communication between two separate data buses

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed interface bridging in portable computing devices
• Voltage level translation in server infrastructure systems
• Data bus interconnects in automotive electronic control units

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DTMR corresponds to the X2SON-8 package and tape-and-reel quantity when ordering. Confirm that the 0.65 V minimum supply requirement aligns with target circuit designs. Ensure ESD protection specifications meet system requirements for handling sensitive logic interfaces during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring ultra-low voltage operation down to 0.65 V and high-speed performance at 1 Gbps. Compare against the SN74AVC2T45 series if lower cost or different packaging is preferred, noting that the AVC series has a higher minimum voltage of 1.2 V and slightly slower speed. Verify thermal dissipation capabilities for the small outline package under maximum load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AXC2T45 family, which represents advanced low-voltage CMOS technology. It serves as a successor to older LVC and AVC families, offering improved speed and lower voltage support. The device is designed to replace legacy translators in modern compact electronics where space and power efficiency are critical constraints.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AVC2T45DCTRE4: Lower speed (500 Mbps) and higher minimum voltage (1.2 V). SN74LVC2T45DCTT: Significantly slower (approx. 17 ns delay) and higher minimum voltage (1.65 V). Direct pin-compatible replacements may require verification of electrical characteristics.
