74ACT11245PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT11245PWR is an octal bus transceiver from the Texas Instruments 74ACT series, designed for high-speed digital signal transmission. It features eight bidirectional data channels with three-state outputs, allowing connection to multiple buses while minimizing power consumption during idle states. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. Packaged in a 20-pin TSSOP format, it provides a propagation delay of 8.9 ns at 5 V, ensuring efficient data transfer in complex electronic systems requiring reliable level shifting and buffering capabilities.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional data path with three-state output capability
• Compatible with TTL input logic levels for broad interface support
• Designed for operation within standard 5 V CMOS voltage ranges

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus architectures requiring signal buffering
• Memory module interfacing and address/data line driving
• General-purpose bidirectional level shifting between logic domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PWR confirms the TSSOP-20 package variant when sourcing. Confirm the 74ACT logic family designation matches system requirements for speed and drive strength. Ensure the 4.5 V to 5.5 V operating voltage aligns with the target board's power distribution network. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal width is required for bidirectional communication rather than unidirectional buffering. The ACT series offers faster switching speeds compared to standard AC or ACT variants, suitable for higher frequency buses. Consider the TSSOP package for space-constrained surface-mount designs. Verify that the 3-state output impedance meets the load requirements of the connected bus lines without additional external drivers.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the widely adopted 74ACT logic family, which bridges the performance gap between older TTL standards and modern CMOS technologies. The 11245 designation specifically indicates an octal transceiver configuration, distinct from hex inverters or quad buffers. It serves as a critical interface element in legacy and industrial systems maintaining 5 V logic compatibility while demanding improved noise immunity and speed over previous generations.
