Dual 8:1 analog multiplexer in a DIP footprint
The Maxim Integrated DG507ACJ+ is a dual 8:1 analog multiplexer (two independent 8-channel muxes on one die) in a 28-pin plastic DIP package for through-hole mounting. Each mux channel presents a maximum on-resistance of 450 Ohm and switches in 1µs (on) and 400ns (off).
450 Ohm on-resistance — what it means for signal integrity
The 450 Ohm max R_on is high by modern standards. For voltage-mode signal switching into a high-impedance load, the 450 Ohm series resistance creates a divider error at DC.
Active lifecycle — no end-of-life risk
The DG507ACJ+ carries an Active product status and is RoHS3 compliant. For a BOM line that requires a through-hole dual 8:1 mux, this part is safe to specify for new designs and production without worrying about a sudden EOL.
