Overview

The SN74LV1T34DCKR is a single-bit, non-inverting buffer and logic level translator designed to bridge different voltage domains in a compact SC-70-5 package. It supports a wide supply range from 1.6V to 5.5V, allowing for seamless up-translation or down-translation between standard logic levels. The output is referenced to the supply voltage, making it a flexible solution for interfacing low-voltage microcontrollers with higher-voltage peripherals or vice versa.

Why Choose This Part

The device features a wide operating temperature range from -40C to 125C and excellent latch-up performance exceeding 250mA. Its CMOS output is compatible with AUP1G and LVC1G families, while the single-gate SC-70 package minimizes board space requirements. It also offers 5V tolerant inputs, which protects the device even when the input voltage exceeds the supply voltage.

Applications

I/O Level Shifting
Translating 1.8V or 3.3V GPIO signals from a processor to 5V logic for driving legacy peripherals.
Signal Buffering
Isolating sensitive signals or providing extra drive strength for long PCB traces in high-speed digital designs.
Mixed-Voltage Systems
Interfacing modern low-power sensors with system-on-chip (SoC) platforms operating at different core voltages.
High-Speed Data Paths
Managing single-bit data signals in paths characterized up to 50MHz at a 3.3V Vcc.

Getting Started

To use this part, connect the Vcc pin to the desired output logic level (1.6V to 5.5V) and ensure the input signal does not exceed 5.5V. Since it is a surface-mount SC-70-5 component, use a compatible breakout board for breadboard prototyping or include it in your PCB layout with standard 0.1uF decoupling capacitors near the Vcc pin.

Also Consider

SN74LVC1G125DCKR TITexas Instruments - Offers a 3-state output option if the signal path needs to be high-impedance (Hi-Z) when disabled.
