SN74LV4051ADBR

Overview

The SN74LV4051ADBR is an 8-channel analog switch manufactured by Texas Instruments. It operates with a supply voltage range of 2.0 V to 5.5 V, ensuring compatibility with low-voltage digital systems. The device features three binary control inputs (A, B, C) that select one of eight independent channels for connection to a common port. It supports bidirectional signal flow and includes logic-compatible input pins. Key electrical characteristics include a maximum on-resistance of 16 ohms at 5 V and low power consumption. The component is housed in a 16-pin TSSOP package, suitable for surface-mount applications requiring efficient space utilization.

• Test and measurement instruments for signal switching

Procurement Notes

Verify the exact ordering suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit products. Confirm temperature range ratings align with your operational environment before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring multiple analog signal paths controlled by digital logic levels. Consider the on-resistance variation and leakage current specifications relative to your signal integrity requirements. Evaluate the package dimensions against your PCB layout constraints. Compare performance metrics with alternative multiplexers if higher bandwidth or lower distortion is necessary for specific application needs.

Part Context

This device belongs to the SN74LV series of low-voltage CMOS logic components. It serves as a multiplexer within Texas Instruments' portfolio of analog switches. The LV family is designed for high-speed operation while maintaining low power consumption. This specific model provides a cost-effective solution for integrating analog switching capabilities into modern digital systems operating at reduced voltage levels.

Replacement Considerations

The SN74LV4051ADR is a direct replacement variant differing primarily in packaging format. Verify pinout compatibility and electrical parameters before substitution. Alternative devices from other manufacturers may require schematic adjustments due to differences in control logic or voltage thresholds. Always consult updated datasheets to ensure functional equivalence in critical applications.
