Overview
The SN74LVC1G19DRLRG4 is a single decoder/demultiplexer from the Texas Instruments LVC logic family. It features one input and two outputs, housed in an SC-70 (SOT-353) surface-mount package. The device operates within a supply voltage range of 1.65 V to 5.5 V and supports propagation delays as low as 2.8 ns at 5 V. It functions across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Provides single-channel decoding or demultiplexing functionality with one input and two outputs.
- Operates across a wide supply voltage range from 1.65 V to 5.5 V for flexible system integration.
- Features high-speed performance with propagation delays down to 2.8 ns at 5 V.
- Designed for surface-mount applications in compact SC-70 packages.
Applications
- Address decoding in embedded systems
- Data routing and signal distribution
- Memory address selection circuits
Procurement Notes
Verify the specific suffix 'R2' against the requested 'R4' variant, as these often denote different reel packaging quantities or tape specifications rather than functional differences. Confirm RoHS compliance status and ensure the SC-70 footprint matches the design layout. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when a single-input, two-output logic gate is required in a minimal footprint. The LVC series offers compatibility with both 1.8 V and 5 V domains. Ensure the application requires only one circuit channel to optimize board space and cost compared to multi-gate alternatives.
Part Context
This part belongs to the SN74LVC1G19 family of single decoders/demultiplexers. It shares the same logical function as the SN74LVC1G19DBVR but differs in the specific reel packaging configuration indicated by the suffix. It is designed for portable and battery-powered applications requiring low power consumption and high speed.
Replacement Considerations
The SN74LVC1G19DBVR is a direct functional equivalent with identical electrical characteristics. Verify if the 'R2' suffix on the DBVR variant meets the specific reel quantity requirements of the production line.
