Overview
The MC74LVXT4051DTG is an analog multiplexer/demultiplexer manufactured by onsemi, utilizing high-performance silicon gate CMOS technology. It features a single 8:1 configuration housed in a TSSOP-16 package. The device operates within a supply voltage range of 2.5 V to 6 V and supports both single and dual supply configurations. Key electrical specifications include a maximum on-resistance of 86 Ohms, a bandwidth of 80 MHz, and propagation delays of 40 ns for both turn-on and turn-off times. It functions across an extended temperature range from -55°C to +125°C.
Feature Summary
- Supports analog signal routing with control over voltage ranges from VCC to VEE
- Compatible pin layout with legacy HC405nA and metal gate MC1405nB devices
- Ensures all analog switches are disabled when the enable pin is held high
Applications
- Signal selection and distribution in electronic systems
- Data acquisition systems requiring analog channel switching
- Communication equipment needing signal path management
Procurement Notes
Verify the specific suffix DTG corresponds to the TSSOP-16 package and tape-and-reel or tube packaging as defined by the manufacturer's current documentation. Confirm RoHS compliance status through official environmental files before integration. Cross-reference the datasheet revision to ensure parameter consistency with existing design libraries.
Selection Notes
Select this component when an 8-channel analog switch is required with low on-resistance and wide bandwidth. The LVXT series offers improved performance over standard LVX variants. Ensure the operating voltage remains within the 2.5 V to 6 V limit and that the thermal environment stays within the -55°C to +125°C operational range for reliable performance.
Part Context
This part belongs to the MC74LVXT4051 family of analog multiplexers. It shares functional similarities with the MC74LVX4051 but utilizes LVXT technology for enhanced speed and lower power consumption. The device serves as a direct replacement for older metal gate MC1405nB designs while offering modern CMOS advantages.
Replacement Considerations
Direct substitutes include the MC74LVX4051DTG for standard LVX performance. For automotive applications, consider the SN74LV4051ATPWRQ1 from Texas Instruments, which offers AEC-Q100 qualification.
