• Compatible with standard TTL logic levels for interface integration

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffered clock signals
• Bidirectional bus transceivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ADBR' corresponds to the SSOP-14 surface-mount package when sourcing. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the intended application falls within the specified 0°C to +70°C temperature range. Cross-reference datasheet electrical characteristics against system requirements before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring multiple buffered outputs with controlled impedance on shared buses. The LS series offers lower power consumption compared to standard TTL variants. Consider the SSOP package dimensions for PCB layout constraints. Evaluate the 3-state enable functionality to manage data flow directionality effectively in complex digital systems.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN54/74(LS)126/25(A) family of quadruple bus buffers. It serves as a complementary device to the SN74LS126, differing primarily in active-high versus active-low enable logic. The 74LS series represents a low-power Schottky variant designed for improved speed-to-power efficiency in legacy digital logic circuits.
