74ACT11244PWR

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74ACT11244PWR is an octal buffer and line driver belonging to the 74ACT logic series. It features eight non-inverting channels with three-state outputs housed in a TSSOP-20 package. The device operates within a supply voltage range of 4.5 V to 5.5 V, ensuring compatibility with TTL input levels and CMOS output levels. Key electrical specifications include a propagation delay of 8.9 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. Static current is specified at 8 uA, with a maximum power dissipation of 1.7 W. The component supports surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight independent non-inverting signal buffering paths with controlled drive capability for system interconnects.
• Integrates three-state output control to facilitate bus-oriented architectures and prevent signal contention during multiplexed operations.
• Maintains TTL-compatible input thresholds while delivering robust CMOS output drive characteristics for reliable logic interfacing.

Buffers, Drivers, Receivers, Transceivers Applications

• Clock distribution networks requiring signal regeneration and isolation.
• Data bus drivers in microprocessor-based systems managing bidirectional data flow.
• Memory address and data line buffering for storage subsystems.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 tape-and-reel packaging configuration required for your assembly process. Confirm that the active status of this part number aligns with your long-term production needs, as availability may vary by distributor. Ensure design files match the exact pinout and thermal characteristics defined in the official datasheet for the PWR variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight buffered channels with precise timing characteristics under standard 5 V logic conditions. The ACT series offers improved speed over legacy LS counterparts while maintaining compatible pinouts. Consider the TSSOP-20 package constraints regarding thermal dissipation and board space if higher channel counts or different form factors are needed.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the broader 74ACT family of advanced CMOS logic devices manufactured by Texas Instruments. It shares functional similarities with other octal buffers like the SN74ACT244 but is distinguished by its specific package type and reel packaging format. The 74ACT series is designed to bridge the performance gap between older bipolar technologies and modern low-voltage CMOS solutions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACT11244DWR serves as a direct functional substitute offering identical electrical specifications in a SOIC-24 package. Designers must verify footprint compatibility and thermal management requirements when transitioning between the TSSOP-20 and SOIC-24 packages.
