Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm that the supply voltage range aligns with your system design before procurement. Check for any recent product lifecycle notices or obsolescence warnings directly from Toshiba Semiconductor and Storage documentation.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing systems requiring multiple independent signal paths with low power consumption. The LCX series is suitable for applications needing fast switching speeds at reduced voltages compared to standard CMOS. Consider the 24 mA drive strength if driving moderate capacitive loads. Verify that the 1.65 V minimum voltage meets your lowest system operating condition.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices from Toshiba. The LCX series is engineered for high-speed operation while maintaining low power dissipation, making it ideal for modern portable and battery-operated equipment. It serves as a direct replacement for older HC/HCT series parts in many 3.3 V designs, offering improved speed and lower voltage tolerance.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for pin-compatible alternatives such as the 74VHC157FT for higher voltage support up to 5.5 V. Verify functional equivalence with other manufacturers' LCX157 variants. Ensure timing parameters meet system requirements when substituting.
