74AC151SJX

Signal Switches, Multiplexers, Decoders Overview

The MC74AC151SJX is an 8-input digital multiplexer manufactured by onsemi, utilizing the AC logic family. It provides a single pole, 8-position switch controlled by three select inputs (S0–S2). The device features both true and complementary outputs and includes an active LOW enable input. It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. The component is housed in a 16-lead Small Outline Package (SOP) with EIAJ TYPE II dimensions.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides high-speed selection of one data line from eight sources
• Generates any logic function of four variables using its universal capability
• Delivers both true and complementary output signals simultaneously

Signal Switches, Multiplexers, Decoders Applications

• Data routing and switching applications
• Universal function generation for logic circuits
• Control information selection systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering code suffix 'X' corresponds to tape and reel packaging as specified in the datasheet. Confirm the manufacturer origin, as this part was originally produced by Fairchild Semiconductor before acquisition by onsemi. Ensure the specific SOP package variant matches the required board layout constraints.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-to-1 multiplexing function is required with low power consumption characteristics typical of the AC series. Consider the ACT variant if TTL-compatible input thresholds are necessary instead of standard CMOS levels. Verify that the 16-lead SOP package fits the available footprint and that the 2.0V to 6.0V supply range aligns with the system design.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74AC151 family of 8-input multiplexers. It shares functional similarities with other members like the 74ACT151 but differs in input threshold specifications. The 'SJX' designation indicates a specific plastic small outline package configuration supplied in tape and reel format for automated assembly processes.
