Overview
The MC74LVXT4053MG is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer manufactured by onsemi. It features three independent single-pole double-throw (SPDT) switches with common off functionality, housed in a 16-pin SOEIAJ package. The device operates within a digital supply voltage range of 2.5 V to 6.0 V and supports an analog power supply range from -3.0 V to +3.0 V relative to ground. Key electrical characteristics include a maximum ON resistance of 86 Ohms at 3.0 V and 26 Ohms at 4.5 V, propagation delays of 40 ns at 2.5 V, and a bandwidth of 80 MHz. It offers low leakage currents, break-before-make switching, and TTL-compatible control inputs.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast propagation speeds and low ON resistance.
- Features channel-select pins compatible with standard TTL logic levels.
- Incorporates break-before-make circuitry to prevent signal shorting during switching.
- Provides improved linearity and lower ON resistance compared to metal-gate or VHC counterparts.
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching applications
- Programmable gain amplifier input selection
- Test and measurement equipment signal paths
Procurement Notes
Verify the specific ordering suffix 'M' corresponds to the SOEIAJ-16 package configuration required for your design. Confirm that the component meets RoHS compliance standards if environmental regulations apply to your manufacturing process. Ensure that the lead pitch and thermal characteristics of the SOEIAJ-16 package are compatible with your PCB footprint and assembly capabilities.
Selection Notes
Select this component when a triple SPDT analog switch with TTL-compatible controls is required. It is suitable for applications needing operation across a wide analog voltage range defined by VCC and VEE supplies. Consider the 86 Ohm maximum ON resistance at lower voltages when designing for low-loss signal paths. Verify that the 125°C maximum operating temperature aligns with your system's thermal environment.
Part Context
This part belongs to the MC74LVXT4053 series of analog multiplexers. It shares pinout compatibility with LVX8053, HC4053A, and MC14053B devices, facilitating drop-in replacements in existing designs. The MG suffix specifically denotes the SOEIAJ-16 package variant, distinguishing it from SOIC or TSSOP versions within the same logical family.
Replacement Considerations
Direct pin-compatible alternatives include MC74LVXT4053DTR2G (SOIC-16) and MC74LVXT4053DT (TSSOP-16). For non-pin-compatible swaps, consider SN74LV4053ATPWREP from Texas Instruments, noting differences in supply voltage limits and package dimensions.
FAQ
How does the Enable pin affect the analog switches?
When the Enable pin is held HIGH, all three analog switches are turned off, placing the outputs in a high-impedance state regardless of the Channel-Select inputs.
What is the maximum analog voltage swing supported?
The analog voltage can vary across the complete power supply range, from VEE to VCC. The positive peak should not exceed VCC, and the negative peak should not go below VEE.
Is the ON resistance constant across the input voltage range?
No, the ON resistance varies with the input voltage. It is more linear than metal-gate CMOS switches but still exhibits variation, with maximum values specified at different VCC voltages in the datasheet.
