74ACT11245DBR

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments SN74ACT11245DBR is an octal bus transceiver featuring three-state outputs, designed for asynchronous communication between two buses. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels with CMOS output levels. The device provides a low-level output current of 24 mA and a high-level output current of -24 mA. It functions reliably across a temperature range of -40°C to +85°C and is housed in a 24-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight bidirectional data paths for efficient bus interfacing
• Three-state outputs enable direct connection to system buses without additional drivers
• Non-inverting logic maintains signal polarity during transmission between buses

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication interfaces between microprocessors and memory systems
• Bus-oriented transfers in industrial control systems
• Data routing in computer peripherals and instrumentation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' confirms the 24-SSOP package and tape-and-reel packaging format. Ensure compatibility with 4.5V to 5.5V power supplies. Confirm RoHS compliance status matches project requirements. Validate that the non-inverting function aligns with the target circuit design before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with three-state outputs is required for 5V logic applications. It is suitable for designs needing TTL-compatible inputs and CMOS-compatible outputs. Consider the SSOP package constraints for PCB layout. Verify that the 24mA drive capability meets the load requirements of the connected bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT family of advanced CMOS logic devices from Texas Instruments. It serves as a bidirectional interface solution, distinct from unidirectional buffers like the 74ACT11244 or latches like the 74ACT11373. The device facilitates data transfer between different bus architectures while maintaining signal integrity through its three-state output capability.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACT11245DWR is a pin-compatible alternative using an SOIC-24 package instead of SSOP. Both parts share identical electrical characteristics and functionality. Verify package dimensions and thermal performance differences when substituting.
