Applications
The SN74AVC1T45DRLR is widely used in mixed-voltage digital systems where logic signals must cross between different power domains, such as microcontroller-to-sensor interfaces and MCU-to-memory bus bridging. It is also employed in portable consumer electronics, wearables, and IoT edge nodes where board space is limited and multiple voltage rails coexist. Additionally, it serves in industrial automation and communications equipment requiring reliable bidirectional signal translation with 3-state bus control.

Frequently Asked Questions
What voltage levels does the SN74AVC1T45DRLR support for voltage translation?
The SN74AVC1T45DRLR supports independent supply voltages from 1.2V to 3.6V on both port A (VCCA) and port B (VCCB), allowing it to translate signals between common logic levels such as 1.8V, 2.5V, and 3.3V without any external components.
What package does the SN74AVC1T45DRLR come in and what are its dimensions?
The SN74AVC1T45DRLR is housed in a 6-pin SOT-363 (R-PDSO-F6) flat-lead package, also known as SC-88 or DRL suffix. This ultra-compact surface-mount package is ideal for designs with stringent board space constraints, commonly found in wearables and mobile devices.
How does the direction control work on the SN74AVC1T45DRLR?
The SN74AVC1T45DRLR uses a single common DIR pin to control the data flow direction across both supply domains. When DIR is high, data flows from port A to port B; when DIR is low, data flows from port B to port A. The OE pin enables or disables the outputs to a high-impedance 3-state condition for bus sharing.
Is the SN74AVC1T45DRLR RoHS compliant and what is its lead-free status?
Yes, the SN74AVC1T45DRLR is fully RoHS compliant and lead-free, as indicated by its Pb-free code (Yes) and JESD-609 code e4. It is suitable for all modern green manufacturing processes and meets international environmental regulations.
