SN74LXC1T14QDCKRQ1

Translators, Level Shifters Overview

The SN74LXC1T14QDCKRQ1 is a single-bit, dual-supply inverting voltage level translator with Schmitt-trigger input. It supports independent VCCI and VCCO rails from 1.1 V to 5.5 V. The device provides up to 32 mA drive strength at 5 V and achieves data rates up to 420 Mbps for 3.3 V to 5.0 V translation. It features glitch-free power sequencing, Ioff partial-power-down support, and overvoltage tolerant inputs. Operating temperature ranges from -40°C to +125°C.

Translators, Level Shifters Feature Summary

• Fully configurable dual-rail design allows each port to operate from 1.1 V to 5.5 V
• Schmitt-trigger inputs allow for slow or noisy inputs
• VCC isolation and Vcc disconnect (Ioff-float) feature
• Glitch-free power supply sequencing

Translators, Level Shifters Applications

• Eliminate slow or noisy input signals
• Driving indicator LEDs or buzzers
• Debouncing a mechanical switch
• General purpose I/O (GPIO) level shifting

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm AEC-Q100 qualification status is required for the target automotive application. Ensure the SC-70-5 footprint aligns with the PCB layout guidelines provided in the datasheet. Check for any recent documentation updates regarding thermal metrics or electrical characteristics before finalizing the bill of materials.

Translators, Level Shifters Selection Notes

Select this component when interfacing devices operating at different interface voltages requiring asynchronous communication. It is suitable for applications needing high drive strength and robust noise immunity via Schmitt triggers. Consider its dual-supply capability for systems where power rails cannot be sequenced simultaneously. Verify that the maximum data rate requirements do not exceed the specified limits for the chosen voltage translation direction.
