SN74LVC4245ADWR

Translators, Level Shifters Overview

The SN74LVC4245ADWR is an octal bus transceiver and voltage level shifter manufactured by Texas Instruments. It features three-state outputs and supports bidirectional data transfer between two independent power domains. The device operates with VCCA ranging from 2.7 V to 3.6 V and VCCB from 2.7 V to 5.5 V, enabling seamless translation between 3.3-V and 5-V logic systems. It utilizes a 24-pin SOIC package (DW) and functions within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Supports asynchronous communication between data buses via direction control inputs
• Enables flexible design by allowing output switching between 3.3-V and 5-V levels without board re-layout
• Provides high noise immunity and latch-up performance exceeding specified current limits

Translators, Level Shifters Applications

• Asynchronous communication between data buses
• Voltage level shifting between 3.3-V and 5-V systems
• Bidirectional voltage translation in industrial environments

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-24 package and tape-and-reel packaging configuration. Confirm that the VCCA supply voltage requirements align with your 3.3-V logic domain, as this variant specifies a maximum VCCA of 3.6 V. Ensure compatibility with RoHS standards if required for your manufacturing process.

Translators, Level Shifters Selection Notes

Select this component when interfacing 3.3-V controllers with 5-V peripherals requiring bidirectional data flow. The dual-supply architecture isolates the A and B sides, protecting lower-voltage logic from higher-voltage signals. Consider the propagation delay characteristics relative to your system's clock speed to ensure signal integrity during transitions.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC4245A family of octal bus transceivers. It shares functional similarities with other LVC series devices but is distinct due to its specific voltage translation capabilities between 3.3-V and 5-V domains. The device is designed for applications requiring robust data transfer across different logic voltage levels.

Translators, Level Shifters Replacement Considerations

SN74LVC4245APWR: Same logical function and pinout but housed in a TSSOP-24 package instead of SOIC-24. Verify footprint compatibility before substitution.
