SN74HCT125DG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT125DG4 is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It belongs to the HCT logic series and utilizes CMOS technology. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features four non-inverting input lines and four corresponding output lines housed in a 14-pin SOIC package. Key electrical parameters include a maximum propagation delay of 36 ns at 4.5 V and 32 ns at 5.5 V. Output drive capabilities are specified as -6 mA for high-level and 6 mA for low-level currents, with a static current of 8 uA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides quad bus buffering functionality with independent control of three-state outputs
• Ensures compatibility with standard TTL logic levels through HCT input structures
• Offers controlled signal transmission via non-inverting buffer gates

Buffers, Drivers, Receivers, Transceivers Applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's official documentation to confirm RoHS compliance status and lead-free manufacturing details. Confirm that the SOIC-14 package dimensions match the target PCB footprint requirements. Ensure the component rating aligns with the intended operating temperature range of -40°C to +85°C before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 5V CMOS logic and TTL-compatible devices requiring buffered signals. The HCT series ensures direct compatibility with standard logic families without level shifting. Consider the 3-state output capability for multiplexed bus applications where multiple drivers share a common line. Verify that the SOIC-14 package is suitable for the available assembly space and thermal management strategy.
