SN74ALVC245PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC245PWR is an octal bus transceiver manufactured by Texas Instruments, belonging to the ALVC logic family. It features three-state outputs and operates within a supply voltage range of 2.5 V to 3.6 V. The device supports bidirectional data transfer between two buses, controlled by direction (DIR) and output enable (OE) inputs. It utilizes a 20-pin TSSOP package and is rated for operation from -40°C to +85°C. Propagation delay is typically 4.5 ns at 3.3 V. Output drive capability is ±24 mA, ensuring robust signal integrity in high-speed digital systems.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional architecture enabling simultaneous data transfer across eight channels
• Three-state outputs allowing effective bus isolation when disabled
• Compatible with standard CMOS and TTL input levels for mixed-voltage system integration

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus architectures requiring low voltage operation
• Memory mapping and buffer applications in embedded systems
• Bidirectional level shifting between 3.3V logic domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the Polymer Reel packaging format required for automated surface-mount assembly. Confirm that the ALVC series specifications align with the target system's 2.5V to 3.6V power rail constraints. Ensure the 20-TSSOP footprint matches the design board layout before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems operating strictly between 2.5V and 3.6V, as it offers faster switching speeds than standard LVC variants. It is suitable for replacing older HC or HCT devices where lower power consumption and higher speed are prioritized over wide voltage tolerance. Verify that the 24mA drive current meets the capacitive load requirements of the connected bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74ALVC family, which provides advanced low-voltage CMOS technology. It serves as a direct functional upgrade to the SN74LVC245, offering improved propagation delays while maintaining similar pinouts. The device is designed for portable and battery-operated applications requiring efficient power management alongside high-performance data transmission capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVC245PWR is a compatible alternative within the same package, though it operates at slightly lower speeds. For broader voltage compatibility including 1.8V, consider the SN74LVC245A variants. Always verify that the replacement maintains the required 20-TSSOP form factor and three-state output characteristics.
