74ACT151SCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT151SCX is an 8-input digital multiplexer in the 74ACT logic series, housed in a 16-lead 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 provides both true and complementary outputs with source/sink capabilities of 24 mA. Propagation delays for select-to-output transitions are typically 3.5 ns at 5.0 V, while enable-to-output delays are approximately 2.5 ns.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides single-pole eight-position switching functionality controlled by three select inputs
• Delivers both true and complementary data outputs simultaneously
• Features TTL-compatible inputs for direct interfacing with standard logic families
• Includes an active-low enable input to control output states

Signal Switches, Multiplexers, Decoders Applications

• Data routing between multiple sources and a single destination
• Implementation of universal function generators for four-variable logic functions
• Selection of control information lines in digital systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering code includes the 'X' suffix to confirm tape and reel packaging availability. Ensure compatibility with the 4.5 V to 5.5 V operating voltage range and check for moisture sensitivity handling requirements during assembly. Confirm the specific package variant matches the design footprint.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-channel multiplexer with high-speed performance and TTL-compatible inputs is required. The ACT series offers reduced quiescent current compared to older AC variants. Consider the 16-lead SOIC package dimensions and thermal characteristics for the target application environment.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices. It implements the standard 8-input multiplexer function defined in the 74xx series specifications. The device is manufactured using FACT technology, ensuring robust performance across industrial temperature ranges.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include the 74AC151SCX (AC series) and equivalents from other manufacturers such as Fairchild's 74ACT151SC or Texas Instruments' CD74AC151M96. Verify pinout compatibility and electrical specifications before substitution.
