SN74LVC4245APWTG4

Translators, Level Shifters Overview

The SN74LVC4245APWTG4 is an octal bus transceiver and voltage-level shifter manufactured by Texas Instruments. It facilitates asynchronous communication between data buses with independent supply rails. The device supports a VCCA range of 4.5 V to 5.5 V and a VCCB range of 2.7 V to 3.6 V, enabling translation from 3.3-V to 5-V systems. It features eight channels in a 24-pin TSSOP package, operating within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides bidirectional data transfer between two independent buses controlled by a direction input signal.
• Functions as a voltage-level shifter allowing seamless interface between 3.3-V and 5-V logic domains without board re-layout.
• Includes three-state outputs that effectively isolate the buses when the output enable input is deactivated.

Translators, Level Shifters Applications

• Mobile phones
• Personal digital assistants
• Handheld terminals

Translators, Level Shifters Procurement Notes

Verify the 'G4' suffix indicates lead-free composition and compliance with RoHS standards. Confirm the package type matches the required 24-TSSOP footprint for PCB integration. Ensure the specific revision level aligns with design requirements. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring robust voltage translation between 3.3-V and 5-V logic families. It is suitable for applications needing high-speed data transfer across isolated power domains. Consider the 24-TSSOP package constraints regarding thermal dissipation and pin pitch. Evaluate the propagation delay specifications against system timing requirements to ensure signal integrity during asynchronous bus operations.

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-shifting capabilities between 3.3-V and 5-V supplies. The G4 suffix denotes environmental compliance, distinguishing it from standard commercial variants while maintaining identical electrical performance characteristics.

Translators, Level Shifters FAQ

What is the primary function of the DIR input?

The DIR input determines the direction of data flow, controlling whether data transfers from the A bus to the B bus or vice versa.

How does the OE input affect operation?

When the OE (Output Enable) input is low, the device operates normally. When high, the outputs are disabled, effectively isolating the buses.
