- Bidirectional single-bit transceiver with 32 mA output sink current in an ultra-compact 6-pin SC70 package measuring 2.0 x 2.1 mm
- Wide operating temperature range from -40°C to 125°C with 15 pF capacitive load capability for robust industrial and automotive designs
Applications
SN74LXCH1T45DCKR is ideal for interfacing mixed-voltage systems in portable electronics, IoT devices, and microcontroller-to-sensor communication where supply rails differ. Its bidirectional level-shifting capability supports I2C, SPI, and GPIO signals between 1.8 V MCUs and 3.3 V or 5 V peripherals. The compact SC70 package makes it well suited for space-constrained PCB designs in wearables and mobile communication equipment.

Frequently Asked Questions
What voltage ranges does SN74LXCH1T45DCKR support for bidirectional level shifting?
SN74LXCH1T45DCKR supports dual-supply voltage-level shifting between 1.2 V and 5.5 V on each side, enabling interfaces between 1.8 V MCU rails and 3.3 V or 5 V peripherals with up to 32 mA output current capability.
What is the package size and pin count of SN74LXCH1T45DCKR for compact PCB designs?
SN74LXCH1T45DCKR comes in a 6-pin SC70 package with a body size of approximately 2.0 x 2.1 mm, making it one of the smallest available single-bit transceiver solutions and ideal for space-constrained wearable and IoT designs.
Which communication protocols benefit from using SN74LXCH1T45DCKR for level translation?
I2C, SPI, UART, and GPIO signal translation applications all benefit from SN74LXCH1T45DCKR. Its 15 pF load capacitance and bidirectional control allow signal integrity across 1.2 V to 5.5 V rails, supporting data rates needed in embedded systems.
How does SN74LXCH1T45DCKR compare to a 2-channel level shifter for single-signal applications?
For single I/O line translation, SN74LXCH1T45DCKR uses just 6 pins in a SC70 package versus a 2-channel device requiring 8+ pins, saving approximately 20% board area while providing 32 mA drive strength and -40°C to 125°C operation.
