8:1 analog multiplexer for precision signal routing
The MAX308EPE+ is a single 8-channel CMOS analog multiplexer from Analog Devices, configured as an 8:1 multiplexer/demultiplexer. It routes one of eight inputs to a common output, controlled by three binary address lines and an enable input. On-state resistance is 100 Ohm max, with channel-to-channel matching of 1.5 Ohm, ensuring consistent attenuation across all paths. Switching times are 150 ns for both turn-on and turn-off, suitable for moderate-speed analog or digital signal switching.
Supply flexibility and signal integrity
The charge injection is 2 pC, minimizing glitch energy during channel transitions. Crosstalk is -92 dB at 100 kHz, indicating strong isolation between channels at moderate frequencies. Off-channel leakage is 750 pA max, and off-channel capacitance is 3 pF (source) and 26 pF (drain), preserving signal fidelity in high-impedance circuits.
Temperature grade and package for through-hole assembly
The supplier device package is 16-PDIP.
