74ACT151SC

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT151SC is an 8-input digital multiplexer housed in a 16-lead Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40°C to +85°C. The device features TTL-compatible inputs, providing both true and complementary outputs with source/sink capabilities of 24 mA. Quiescent supply current is limited to 40 µA at maximum voltage.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'X' if tape and reel packaging is required, as standard units may differ. Confirm that the component meets RoHS compliance standards before integration. Ensure the selected package variant matches the intended PCB footprint requirements for the 16-lead SOIC form factor.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a high-speed 8-to-1 data path is necessary. The ACT series ensures compatibility with TTL logic levels while maintaining CMOS performance characteristics. Verify that the 24 mA drive capability meets the load requirements of the destination circuitry.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the AC/ACT151 family of 8-input multiplexers originally documented by Fairchild Semiconductor. The 74ACT151SC specifically denotes the narrow-body SOIC package version. It serves as a standard logic solution for routing signals in digital systems requiring parallel-to-serial conversion or address decoding.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with other manufacturers offering the 74ACT151 specification. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength against the original datasheet specifications.

Signal Switches, Multiplexers, Decoders FAQ

What is the function of the Enable input?

The Enable input (E) is active LOW. When not activated, the complementary output is HIGH and the true output is LOW regardless of other inputs.

How are the outputs configured?

Both true and complementary outputs are provided, allowing for flexible signal routing and inversion without external components.
