SN74LV245ANSRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ANSRG4 is an octal bus transceiver from Texas Instruments featuring three-state outputs. It operates within a supply voltage range of 2 V to 3.6 V and supports mixed-mode operation across all ports. The device utilizes LVCH logic technology, providing a typical propagation delay of 7 ns. It is housed in a 20-pin VQFN package and functions as a non-inverting bidirectional data translator with common control for direction and output enable signals.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode voltage operation allowing simultaneous use of 3.3-V and 5-V signaling on different ports
• Provides partial power-down mode capability via Ioff circuitry to prevent backflow current when the device is de-energized
• Features low noise design characteristics including controlled output swing and reduced ground bounce

Buffers, Drivers, Receivers, Transceivers Applications

• Memory module interfaces requiring bidirectional data transfer
• Consumer electronics utilizing mixed-voltage logic domains
• Industrial control systems needing isolated bus communication

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SRG4' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the ordering part number matches the required RoHS compliance status and moisture sensitivity level defined in the latest product data sheet before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require bidirectional data flow between buses operating at different voltage levels within the 2 V to 3.6 V range. The LVCH series offers improved noise immunity compared to standard LVC devices. Consider the VQFN package constraints regarding thermal dissipation and PCB layout requirements for optimal signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCH245A family of octal bus transceivers. It shares functional similarities with other members like the SN74LV245A but differs in specific electrical characteristics such as supply voltage limits and noise performance. The 'G4' suffix typically indicates lead-free and RoHS-compliant manufacturing standards consistent with Texas Instruments' product line updates.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the SN74LVCH245ADBR and SN74LVCH245ADRLR. Verify that alternative parts maintain the same 2 V to 3.6 V operating range and VQFN-20 footprint to ensure seamless integration without schematic modifications.
