Key Features
- Single 1-of-2 decoder/demultiplexer routes one input signal to either of two outputs under select and enable control, ideal for signal routing in compact logic designs
- Wide supply voltage range of 1.65V to 5.5V in the LVC logic family enables direct interfacing between 1.8V, 3.3V, and 5V logic systems without level shifters
- Ultra-compact 6-pin SOT-23 package minimizes PCB footprint, making it ideal for wearable devices, IoT nodes, and space-constrained mobile electronic designs
Applications
The SN74LVC1G19DCKR-P is used in digital signal routing circuits where a single data or control signal needs to be directed to one of two destinations based on a select line, such as in bus switching, I2C address selection, and GPIO demultiplexing in microcontroller systems. Its compact SOT-23 package and wide voltage range make it ideal for portable consumer electronics, wearables, and IoT sensor nodes requiring minimal board space. It is also applied in test and measurement equipment and communication interfaces where controlled signal distribution between two output paths is needed.

Frequently Asked Questions
What is the function of the SN74LVC1G19DCKR-P?
The SN74LVC1G19DCKR-P is a 1-of-2 decoder and demultiplexer that routes a single input signal to one of two outputs based on the state of a select input and an active-low enable pin. When disabled, all outputs are driven high, providing a convenient way to isolate signals from the output bus in a compact single-gate IC.
What supply voltage range does the SN74LVC1G19DCKR-P support?
The SN74LVC1G19DCKR-P operates from a supply voltage of 1.65V to 5.5V as part of the LVC (Low Voltage CMOS) logic family. This wide range enables direct interfacing with 1.8V, 2.5V, 3.3V, and 5V logic systems, making it suitable for mixed-voltage designs in modern embedded and IoT applications.
What package does the SN74LVC1G19DCKR-P come in?
The SN74LVC1G19DCKR-P is housed in a 6-pin SOT-23 (SC-74A) surface-mount package, which measures approximately 2.9 mm x 1.6 mm. This very small package is ideal for space-constrained PCB designs in portable electronics, wearable devices, hearing aids, and other miniaturized products where component footprint must be minimized.
What does the '-P' suffix mean in SN74LVC1G19DCKR-P?
The '-P' suffix in SN74LVC1G19DCKR-P typically indicates a specific product variant designation used by Texas Instruments for certain distribution or qualification channels. Designers should confirm the datasheet for the specific variant to verify any differences in qualification level, packaging, or temperature ratings compared to the standard SN74LVC1G19DCKR.
What are common applications for the SN74LVC1G19DCKR-P decoder?
Common applications include I2C and SPI bus address demultiplexing, GPIO signal routing in microcontroller designs, display segment switching, and sensor channel selection in battery-powered devices. The device also finds use in test fixtures, communication interfaces, and logic control circuits where selective signal distribution between two output paths is required in a single compact IC.
