SN74LXC1T45DCKR

Translators, Level Shifters Overview

The SN74LXC1T45DCKR is a single-bit, dual-supply, non-inverting bidirectional voltage-level bus transceiver manufactured by Texas Instruments. It operates with independent supply rails VCCA and VCCB ranging from 1.1V to 5.5V, enabling flexible translation between diverse logic families. The device supports data rates up to 420Mbps when operating at 3.3V to 5.0V. It features Schmitt-trigger inputs for noise immunity and integrated dynamic pull-down resistors on I/O pins. The component is housed in a compact SC-70-6 surface-mount package.

Translators, Level Shifters Feature Summary

• Dual-supply architecture allows independent configuration of A and B ports across the full 1.1V to 5.5V range
• Integrated dynamic pull-down resistors on I/O pins reduce external component requirements
• Schmitt-trigger inputs provide robust noise immunity for slow or noisy signals
• Supports partial power-down modes via VCC isolation and Ioff-float capabilities

Translators, Level Shifters Applications

• Asynchronous communication between data buses operating at different voltage levels
• Portable systems requiring low-power operation and flexible voltage translation
• Embedded controllers interfacing with peripherals using mixed logic standards

Translators, Level Shifters Procurement Notes

Verify the specific suffix DCKR corresponds to the SC-70-6 tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 1.1V to 5.5V operating range for both supply rails to maintain signal integrity.

Translators, Level Shifters Selection Notes

Select this component for applications requiring high-speed translation up to 420Mbps with minimal external circuitry. The integrated pull-downs simplify PCB layout compared to devices requiring external resistors. Consider the SC-70-6 package size constraints and verify thermal performance within the -40°C to +125°C operating temperature range for the target environment.

Translators, Level Shifters Part Context

This device belongs to the SN74LXC1T45 family of single-bit dual-supply bus transceivers. It complements other LVC and AVC series components by offering extended voltage flexibility down to 1.1V while maintaining high drive strength. The family is designed for general-purpose level shifting in complex multi-voltage digital systems.
