- Common direction control simplifies board design with a single DIR pin for both channels
- Low 15pF load capacitance for high-speed signal integrity in data bus translation applications
- 32mA output sink current providing robust drive strength for bus lines with multiple loads
Applications
The SN74LXC2T45DCUR is used to translate logic signals between different voltage domains in mixed-supply embedded systems, such as connecting a 1.8V microcontroller to 3.3V peripherals. It is commonly found in I2C, SPI, and general-purpose GPIO level-shifting circuits in IoT modules, wearables, and single-board computers. Its bidirectional architecture and compact SOIC-8 package reduce component count in two-way signal path designs.

Frequently Asked Questions
What is the SN74LXC2T45DCUR used for?
The SN74LXC2T45DCUR is a dual-channel bidirectional bus transceiver used for voltage-level translation between different logic domains, such as 1.8V and 3.3V, in embedded and IoT systems requiring mixed-voltage interfacing.
What voltage levels does the SN74LXC2T45DCUR support?
The SN74LXC2T45DCUR supports supply voltages from 1.2V to 5.5V on each port independently, making it highly flexible for translating between virtually any common logic voltage levels used in modern electronics.
How is the direction of data flow controlled in the SN74LXC2T45DCUR?
Both channels share a common direction control (DIR) pin. Setting DIR high enables data flow from port A to port B, and setting it low reverses the direction, simplifying bidirectional bus control with a single signal.
What package does the SN74LXC2T45DCUR come in?
The SN74LXC2T45DCUR is housed in an 8-pin Small Outline (SOIC) package, offering a compact surface-mount footprint suitable for high-density PCB designs and automated assembly processes.
Is the SN74LXC2T45DCUR lead-free and RoHS compliant?
Yes, the SN74LXC2T45DCUR carries a Pb-free designation, confirming it is manufactured without lead and complies with RoHS environmental directives, making it suitable for regulated consumer and industrial markets.
