MAX4514CUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4514CUK-T is a single-pole/single-throw (SPST), CMOS, low-voltage analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply between +2V and +12V and handles rail-to-rail analog signals. The device features very low on-resistance of 20Ω at +5V and 10Ω at +12V. Off-leakage current is guaranteed at 1nA at +25°C and 20nA at +85°C. On-leakage current is 2nA at +25°C and 40nA at +85°C. Charge injection is 10pC. Switching speeds are tON = 150ns and tOFF = 100ns. It utilizes break-before-make operation and is compatible with TTL/CMOS logic at +5V. The component is housed in an SOT23-5 package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUK' corresponds to the commercial temperature range and SOT23-5 package configuration as documented in official Maxim Integrated ordering information. Ensure the tape-and-reel specifications match the required manufacturing process. Confirm RoHS compliance status through the manufacturer's certification documents before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-channel SPST switch is required for low-voltage applications. Consider the 20Ω on-resistance at +5V for signal path losses. Evaluate the 150ns turn-on time against system timing requirements. Verify that the SOT23-5 footprint fits the PCB layout constraints. Check if the commercial temperature range meets the environmental operating conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4514 belongs to the MAX4514/MAX4515 family of low-voltage, low-on-resistance, SPST CMOS analog switches. The MAX4514 variant is specifically designed as a normally open switch, whereas the MAX4515 is normally closed. Both share identical pinouts and electrical characteristics, differing only in their default state. This family serves as a compact solution for signal routing in space-constrained designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4516 and MAX4517 are pin-compatible alternatives designed for dual-supply operation. These parts support voltage ranges between ±1V and ±6V. Engineers should verify power supply availability and signal polarity requirements when considering these substitutes for single-supply designs.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic threshold behavior at different supply voltages?

At +5V, the digital inputs have 0.8V to 2.4V thresholds ensuring TTL/CMOS compatibility. As the supply voltage increases to +12V, the high-level threshold rises to approximately 3.0V, maintaining CMOS compatibility.

How does the device handle overvoltage on analog pins?

Internal reverse ESD-protection diodes connect each analog-signal pin to V+ and GND. If any analog signal exceeds V+ or GND, one of these diodes conducts, clamping the voltage.

What is the off-isolation performance in 50Ω systems?

In 50Ω systems, off-isolation is approximately -45dB at 10MHz. Performance decreases by approximately 20dB per decade as frequency increases due to capacitive coupling.
