Key Features
- Dual-supply architecture supports independent VCCA (1.65–3.6V) and VCCB (1.65–5.5V) voltage rails for flexible level translation
- 2-bit bidirectional voltage-level translation with direction controlled by OE and DIR pins
- 3-state outputs allow easy bus sharing and high-impedance mode when OE is asserted low
- Ultra-small DSBGA-8 (YZP) package ideal for space-constrained mobile and wearable designs
- LVC logic family ensures low-voltage CMOS compatibility with fast switching speeds and low power consumption
Applications
SN74LVC2T45YZPR is widely used in mixed-voltage digital systems where interfaces between 1.8V microcontrollers and 3.3V or 5V peripherals require bidirectional level shifting. It is commonly found in smartphones, tablets, IoT sensors, and portable medical devices that demand compact footprints and multi-rail power domains. The device also suits UART, SPI, and I2C bus bridging applications in industrial controllers and embedded computing platforms.

Frequently Asked Questions
What voltage levels does the SN74LVC2T45YZPR support?
The SN74LVC2T45YZPR supports VCCA from 1.65V to 3.6V and VCCB from 1.65V to 5.5V, enabling level translation between common logic standards such as 1.8V, 2.5V, 3.3V, and 5V CMOS systems.
How is the data direction controlled on the SN74LVC2T45YZPR?
Data direction is controlled by the DIR pin: 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, placing them in a high-impedance state when OE is low.
What package does the SN74LVC2T45YZPR use and what are its dimensions?
The SN74LVC2T45YZPR comes in an 8-ball DSBGA (YZP) package with a footprint of approximately 1.02 mm × 0.92 mm, making it one of the smallest available options for dual-bit bus transceivers suitable for high-density PCB designs.
What are typical applications for the SN74LVC2T45YZPR?
Typical applications include bidirectional voltage translation on SPI, UART, and I2C buses in smartphones, wearables, IoT nodes, and portable medical devices where space is limited and multiple supply voltages coexist on the same PCB.
Is the SN74LVC2T45YZPR compatible with 5V-tolerant inputs?
Yes, the B-port inputs of the SN74LVC2T45YZPR are 5V tolerant when VCCB is supplied, allowing direct interfacing with legacy 5V logic while the A port operates at lower voltages down to 1.65V without requiring additional protection components.
