74ALVC164245DGGRG4

Overview

The SN74ALVC164245DGGRG4 is a 16-bit (dual octal) non-inverting bus transceiver with level-shifting capabilities, manufactured by Texas Instruments. It operates within the ALVC logic family and features two independent power supply rails: VCCA supports 2.3 V to 3.6 V, while VCCB supports 3.0 V to 5.5 V. The device provides bidirectional data transfer between these voltage domains with a maximum data rate of 300 Mb/s and a propagation delay of 2.4 ns. It utilizes a 48-pin TSSOP package, offers three-state outputs, and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual independent power supply architecture enabling seamless translation between 2.5V/3.3V and 3.3V/5V logic environments
• High-speed asynchronous communication support with a maximum data throughput of 300 Mb/s
• Bidirectional data flow control via dedicated direction pins for flexible system integration
• Robust noise immunity provided by Schmitt-trigger inputs at both ports A and B

Applications

• Asynchronous communication between microprocessors and memory modules operating at different voltage levels
• Signal translation in high-density consumer electronics and industrial control systems
• Data bus interfacing in telecommunications infrastructure equipment
• Level shifting for peripheral devices requiring mixed-voltage compatibility

Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's current datasheet to confirm RoHS compliance status and lead time requirements. Ensure the ordering part number matches the exact package type and temperature grade specified in your design documentation. Cross-reference the component marking with official factory labels to prevent counterfeit substitution during assembly.

Selection Notes

Select this component when designing systems that require bidirectional data transfer between 2.5V or 3.3V sources and 3.3V or 5V destinations. The ALVC series is appropriate for applications demanding low power consumption alongside high-speed performance. Confirm that the 48-pin TSSOP footprint aligns with your PCB layout constraints and thermal management strategy before finalizing the bill of materials.

Part Context

This device belongs to the SN74ALVC164245 family of level-shifting transceivers. It shares functional similarities with other members like the SN74ALVC164245DLR but differs in packaging and specific manufacturing revisions. The DGGR variant specifically denotes the TSSOP-48 package configuration, distinguishing it from SSOP or BGA options within the same logical family.

Replacement Considerations

The SN74ALVC164245DGGRE4 serves as a direct equivalent replacement, offering identical electrical characteristics and pinout compatibility. Verify that any substitute maintains the same ALVC logic family specifications and package dimensions to ensure seamless integration without redesigning the host circuit board.
