SN74LVC1T45DCKR-P

Translators, Level Shifters Overview

The SN74LVC1T45DCKR-P is a single-bit dual-supply bus transceiver manufactured by Texas Instruments. It facilitates bidirectional data transmission between two buses operating at different voltage levels, supporting logic high voltages from 1.2V to 3.6V on port A and 1.2V to 5.5V on port B. The device incorporates a direction control pin (DIR) to manage signal flow and an output enable pin (OE) for controlling the output state. Designed for low-voltage applications, it ensures compatibility across mixed-voltage systems while maintaining signal integrity through controlled slew rates.

Translators, Level Shifters Feature Summary

• Supports bidirectional data transfer between buses with independent supply voltages
• Includes dedicated direction control and output enable pins for flexible system management
• Compatible with low-voltage logic families ranging from 1.2V to 5.5V

Translators, Level Shifters Applications

• Mixed-voltage interface circuits in portable electronics
• Bidirectional level shifting between microcontrollers and peripheral devices
• Memory interfaces requiring voltage translation

Translators, Level Shifters Procurement Notes

Verify the exact part number against official Texas Instruments documentation to ensure authenticity. Confirm that the suffix 'P' corresponds to the specified package type and tape-and-reel configuration as defined in the manufacturer's ordering information. Cross-reference the date code and lot markings with authorized distributor records to prevent counterfeit components. Ensure compliance with RoHS directives if required for your specific application environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic circuits operating at different voltage domains, specifically where one side requires lower voltage than the other. Consider the maximum data rate and propagation delay specifications relative to your system clock requirements. Evaluate the power consumption characteristics if battery life is a critical constraint in the design.

Translators, Level Shifters Part Context

This device belongs to the SN74LVC1T series of single-bit bus transceivers. It is part of a broader family designed for low-voltage CMOS technology, offering improved performance over older LVC variants. The DCKR package indicates a small-outline transistor case with specific lead pitch dimensions suitable for surface-mount assembly processes.

Translators, Level Shifters Replacement Considerations

Check for direct pin-compatible alternatives within the same LVC family or newer generations such as the SN74AVC series for higher speed requirements. Verify that any substitute supports the same voltage ranges on both ports and maintains similar electrical characteristics like propagation delay and drive strength.
