74ACT151SJ

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT151SJ is an 8-input digital multiplexer housed in a 16-lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm wide. It operates within a supply voltage range of 4.5V to 5.5V and supports temperatures from -40°C to +85°C. The device provides both true and complementary outputs with TTL-compatible inputs. Propagation delays for select-to-output transitions are typically 12.5 ns at 5.0V, while enable-to-output delays are approximately 6.0 ns.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides high-speed selection of one data line from eight sources
• Features TTL-compatible inputs for direct interface with logic systems
• Delivers both true and complementary output signals simultaneously

Signal Switches, Multiplexers, Decoders Applications

• Universal function generator for four-variable logic functions
• Data routing and switching in digital circuits
• Control information selection in system architectures

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific SOP package dimensions against the EIAJ TYPE II standard to ensure mechanical compatibility. Confirm that the operating environment remains within the specified -40°C to +85°C temperature range. Ensure power supply stability between 4.5V and 5.5V to maintain signal integrity and prevent damage to the internal circuitry during operation.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-pole, eight-position switch functionality is required within a compact surface-mount footprint. The ACT series offers reduced quiescent current compared to older AC variants while maintaining high-speed performance. Verify that the load capacitance requirements do not exceed the specified limits to avoid excessive propagation delay variations.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74ACT family of high-speed CMOS logic components. It serves as a direct replacement for legacy 74LS151 devices in modern designs requiring lower power consumption and faster switching speeds. The SOP-16 package allows for efficient board space utilization in dense electronic assemblies.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include the Fairchild/ON Semiconductor 74ACT151SC (SOIC) and 74ACT151PC (PDIP). These alternatives share identical logical functionality but differ in physical package geometry. Verify pinout alignment and thermal characteristics before substituting.
