MC74LVX8053M

Overview

The MC74LVX8053M is a triple single-pole double-position (SPDT) analog multiplexer/demultiplexer manufactured by onsemi using high-performance silicon-gate CMOS technology. It operates within an analog and digital power supply range of 2.5 V to 6.0 V. The device features fast propagation delays, low ON resistance, and low OFF leakage currents. Key electrical parameters include a maximum ON resistance of 40 Ω at 3.0 V and 25 Ω at 5.5 V, with a channel-to-channel matching difference of 15 Ω. Propagation delay from channel select to analog output is 30 ns at 3.0 V and 15 ns at 5.5 V. The bandwidth is 120 MHz, and crosstalk is -60 dB at 1.0 MHz. It is housed in a 16-pin SOEIAJ package.

Feature Summary

• Triple SPDT configuration allowing independent control of three analog switches
• Silicon-gate CMOS technology providing improved linearity and lower ON resistance compared to metal-gate counterparts
• Diode protection included on all inputs and outputs for enhanced robustness
• Compatible with standard CMOS outputs and LSTTL outputs when pull-up resistors are used

Applications

• Signal routing in data acquisition systems
• Audio signal switching and processing
• Video signal selection and distribution
• Test and measurement equipment requiring analog signal multiplexing

Procurement Notes

Verify the specific ordering suffix 'M' corresponds to the SOEIAJ-16 package variant. Confirm RoHS compliance status if required, as Pb-free versions exist under the 'MG' suffix. Ensure the application environment stays within the specified operating temperature range of -55°C to +85°C. Check for any specific handling requirements related to static-sensitive CMOS devices during assembly.

Selection Notes

Select this component when a triple SPDT analog switch is needed with low distortion and high bandwidth. It serves as a pin-compatible alternative to HC4053A and MC14053B devices. Consider the 2.5 V to 6.0 V supply range suitability for the system voltage. Evaluate the 120 MHz bandwidth against the highest frequency signals to be switched. Verify that the 16-pin SOEIAJ package fits the PCB layout constraints.

Part Context

This device belongs to the LVX series of analog multiplexers from onsemi, designed for high-speed applications. It shares functional similarities with other LVX family members but offers specific triple SPDT topology. The technology leverages silicon-gate CMOS for superior performance metrics over older metal-gate technologies. It is part of a broader portfolio of logic and analog switching solutions.

Replacement Considerations

HC4053A: Pin-compatible CMOS analog switch with similar functionality but potentially different speed and resistance characteristics. MC14053B: Metal-gate counterpart offering comparable switching capabilities but with higher ON resistance and slower speeds. Verify electrical parameter compatibility before substitution.

FAQ

What is the maximum analog input voltage allowed?

The maximum analog input voltage is equal to the positive DC supply voltage (VCC). The input voltage must remain between GND and VCC.

How does the device handle unused channels?

Unused analog inputs/outputs may be left floating. However, tying them to VCC or GND through a low-value resistor can help minimize crosstalk and feedthrough noise.

Is the device compatible with LSTTL logic levels?

Yes, the Channel-Select and Enable inputs are compatible with LSTTL outputs when pull-up resistors are used.
