SN74LVC4245ADWRG4

Translators, Level Shifters Overview

The SN74LVC4245ADWRG4 is an octal bus transceiver with three-state outputs from the Texas Instruments LVC logic family. It operates within a supply voltage range of 2.0 V to 3.6 V on both A and B buses, supporting TTL/CMOS input levels and LVTTTL output levels. The device features a propagation delay of 6.5 ns and provides a low-level output current of 24 mA. It is housed in a 20-pin SOIC package and functions across a temperature range of -40°C to +125°C.

Translators, Level Shifters Feature Summary

• Provides bidirectional data transfer between two independent 8-bit buses using a single direction control signal.
• Supports asynchronous communication protocols through tri-state outputs that effectively isolate the bus when disabled.
• Enables flexible system design by allowing direct switching between standard 3.3-V and 5-V configurations without board layout changes.

Translators, Level Shifters Applications

• Asynchronous communication between data buses
• Memory and memory mapping applications
• High-speed data acquisition systems

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'G4' indicates lead-free manufacturing compliance with RoHS standards. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply specifications before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component for designs requiring robust bidirectional data transfer with high noise immunity. The wide operating temperature range makes it suitable for industrial environments. Consider the propagation delay and output drive strength when designing for high-speed digital interfaces or long trace lengths.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC4245A series of octal bus transceivers. It shares functional similarities with other LVC family devices but is distinguished by its specific voltage range and package configuration. The G4 suffix typically denotes environmental compliance, differentiating it from standard commercial variants.

Translators, Level Shifters Replacement Considerations

Direct replacements include SN74LVC4245ADWR and SN74LVC4245APWR. Verify pin compatibility and electrical characteristics before substitution. Alternative packages such as TSSOP may require adapter solutions if physical footprint constraints differ.
