Frequently Asked Questions
What voltage levels does the SN74AXC1T45DRLR support for logic translation?
The SN74AXC1T45DRLR supports bidirectional voltage translation between 0.8V and 3.6V on both the A and B ports, making it compatible with 0.9V, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V logic families commonly used in modern digital systems.
What is the maximum output sink current (I_OL) of the SN74AXC1T45DRLR?
The SN74AXC1T45DRLR has a maximum output sink current (I_OL) of 12mA (0.012A), which is suitable for driving standard CMOS and TTL logic inputs in typical digital interface applications with load capacitances up to 50pF.
In what package does the SN74AXC1T45DRLR come, and what are its key dimensions?
The SN74AXC1T45DRLR is available in a 6-pin SOT-23 flat lead package (JESD-30 code R-PDSO-F6), which is a very compact surface-mount package ideal for space-constrained PCB designs in portable electronics, wearables, and IoT devices.
Can the SN74AXC1T45DRLR be used as a replacement for other single-bit bus transceivers?
Yes, the SN74AXC1T45DRLR from Texas Instruments' AXC family is pin-compatible and functionally equivalent to similar single-bit dual-supply bus transceivers from other manufacturers, provided the target device supports the same voltage range (0.8V to 3.6V) and uses a compatible 6-pin SOT-23 package.
When was the SN74AXC1T45DRLR introduced, and is it still in production?
The SN74AXC1T45DRLR was introduced on 2017-12-03 and has an estimated years to end-of-life (YTEOL) of 15 years, indicating it is a long-lifecycle product actively supported by Texas Instruments and expected to remain in production well into the future.
