Key Features
- Bidirectional voltage-level shifting between 1.65V–5.5V supply rails with no external resistors required
- 32mA output drive strength (I_OL) enables robust signal integrity across mixed-voltage interfaces
- Ultra-compact SOT23-6 package minimizes PCB footprint for space-constrained designs
- 3-state outputs allow easy bus sharing and high-impedance disable for multi-device topologies
Applications
The SN74LVC1T45DBVT is widely used in mixed-voltage digital systems where microcontrollers, FPGAs, or SoCs at different logic levels must communicate reliably. Common applications include level shifting between 3.3V MCUs and 5V peripherals, I2C or SPI bus bridging in IoT and industrial designs, and interface translation in portable consumer electronics and embedded computing platforms.

Frequently Asked Questions
What voltage levels does the SN74LVC1T45DBVT support for level shifting?
The SN74LVC1T45DBVT supports voltage-level shifting between supply voltages ranging from 1.65V to 5.5V on both the A and B ports independently, making it compatible with 1.8V, 2.5V, 3.3V, and 5V logic families without any external components.
Can the SN74LVC1T45DBVT operate in both directions on the same bus?
Yes, it is a bidirectional transceiver. The direction of data transfer is controlled by the DIR pin: driving DIR high transfers data from A to B, while driving it low transfers data from B to A, enabling full two-way communication over a single bus.
What is the output drive current of the SN74LVC1T45DBVT?
The SN74LVC1T45DBVT provides a maximum output low current (I_OL) of 32mA, which ensures strong signal drive capability and compatibility with standard logic loads and line capacitances up to 15pF.
What package does the SN74LVC1T45DBVT come in and how small is it?
It is available in a SOT23-6 (6-pin small-outline transistor) package, one of the smallest logic IC packages available, making it ideal for space-constrained PCB layouts in portable, wearable, and handheld devices.
