SN74LVC1G29SYZPR

Overview

The SN74LVC1G29SYZPR is a single 2-of-3 decoder/demultiplexer manufactured by Texas Instruments. It operates with a supply voltage range of 1.65 V to 5.5 V and features inputs that accept voltages up to 5.5 V, ensuring compatibility with 5-V systems even when powered at lower levels. The device supports partial-power-down mode and provides back-drive protection for its outputs. Packaged in an SC-70 (SOT-353) surface-mount case, it is designed for low-voltage applications requiring efficient signal routing and decoding functions.

Feature Summary

• Supports 5-V VCC operation while accepting 5.5 V input voltages
• Enables partial-power-down mode to reduce power consumption
• Provides back-drive protection on output pins

Applications

• Low-voltage digital signal routing
• Decoder and demultiplexer circuits in portable electronics
• System interface logic where mixed voltage domains are present

Procurement Notes

Verify the component status as Active directly from official Texas Instruments documentation before procurement. Confirm the package type matches the required SC-70 footprint. Ensure that the specific suffix aligns with your manufacturing requirements. Cross-reference the datasheet revision date to guarantee compliance with current design specifications and electrical characteristics.

Selection Notes

Select this component when a single-channel decoder or demultiplexer is needed for low-voltage logic families. It is suitable for designs requiring input tolerance above the supply voltage. Consider the SC-70 package size for space-constrained layouts. Verify that the operating voltage range meets the system's power supply constraints and that back-drive protection is necessary for the application.

Part Context

This part belongs to the SN74LVC1Gxx series of single-gate logic devices from Texas Instruments. These components are designed for high-speed, low-power applications using LVC technology. The series offers various logic functions in compact packages, catering to modern electronic devices that require minimal board space and efficient power management capabilities.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Ensure any replacement maintains the same 2-of-3 decoder functionality and compatible voltage ranges. Verify pinout compatibility to avoid redesigning the PCB layout.
