Overview
The SN74LVC1G19DBVR is a non-inverting 1-to-2 demultiplexer manufactured by UMW in an SOT-23-5 package. It operates within a supply voltage range of 1.65V to 5.5V and supports mixed voltage levels including 1.65V, 2.3V, 3.0V, and 5.5V via overvoltage tolerance on I/O pins. The device features high-speed propagation delay with typical values of 2.9ns at 3.3V under a 50pF load, and offers output drive capability up to 32mA. Quiescent supply current is typically 10µA at 5.5V.
Feature Summary
- Provides non-inverting 1-to-2 demultiplexing functionality with data routing controlled by a select input.
- Features overvoltage tolerance (OVT) circuitry on I/O pins for mixed-voltage board buffering applications.
- Delivers high output drive capability of 32mA while maintaining low quiescent power consumption.
Applications
- On-board buffering for mixed voltage systems
- Data routing in portable devices
- Signal distribution in consumer electronics
Procurement Notes
Verify the manufacturer marking code CYUC or CYFU against the specific order code SN74LVC1G19DBVR to confirm UMW origin. Ensure the component is RoHS compliant and Pb-free as specified. Confirm the SOT-23-5 package type matches the design footprint requirements before integration.
Selection Notes
Select this component when a single-channel non-inverting demultiplexer is required for low-power logic applications. The SOT-23-5 package provides space efficiency for compact designs. Consider the 1.65V to 5.5V operating range and OVT capabilities if interfacing between different voltage domains.
Part Context
This part belongs to the 74LVC family of logic integrated circuits, designed for low-voltage CMOS applications. The SN74LVC1G19 series specifically addresses the need for compact, high-performance demultiplexers in modern electronic systems requiring minimal power consumption and small form factors.
Replacement Considerations
Compatible alternatives include the SN74LVC1G19DBVR from Texas Instruments and the 74LVC1G19GW-Q100H from Nexperia. Verify pinout compatibility and electrical specifications such as propagation delay and drive current before substitution.
