SN74LXC1T14DCKR

Translators, Level Shifters Overview

The SN74LXC1T14DCKR is a single-bit, dual-supply inverting voltage level translator manufactured by Texas Instruments. It features Schmitt-trigger inputs and operates with independent VCCI and VCCO supply rails ranging from 1.1 V to 5.5 V. The device supports data rates up to 420 Mbps during 3.3 V to 5.0 V translation. It includes Ioff protection for partial power-down applications and glitch-free power sequencing. The component is housed in a SC-70 (DCK) package.

Translators, Level Shifters Feature Summary

• Dual-rail design allows independent configuration of input and output supply voltages
• Schmitt-trigger inputs provide noise immunity for slow or noisy signals
• Integrated dynamic pull-down resistors reduce the need for external components
• Ioff circuitry prevents current backflow during partial power-down states

Translators, Level Shifters Applications

• Eliminating slow or noisy input signals
• Driving indicator LEDs or buzzers
• Debouncing mechanical switches
• General purpose I/O level shifting

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix DCKR against the manufacturer's official orderable addendum to confirm the SC-70 package and tape-and-reel packaging format. Ensure that the selected variant matches the required thermal and electrical specifications for the target application environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing devices operating at different logic levels requiring asynchronous translation. The dual-supply architecture is suitable for systems where input and output domains differ. Verify that the required data rate does not exceed the maximum supported speed for the specific voltage translation direction.

Translators, Level Shifters FAQ

How does the device handle power supply sequencing?

The device features glitch-free power supply sequencing, allowing either supply rail to be powered on or off in any order without producing glitches on the output.

What is the function of the integrated dynamic pull-down resistors?

These resistors help prevent floating inputs during disabling by driving the input low before the output becomes high impedance, reducing the need for external pull-down components.
