The MAX349CAP+ is a single 8:1 CMOS analog multiplexer. On-resistance is 100 Ohms max, channel-to-channel matching 16 Ohms max.
The MAX349CAP+ carries an Active lifecycle status and is ROHS3 compliant. No direct pin-compatible second source is listed in the official record, but the 8:1 mux function is common across the Maxim CMOS mux family; verify any alternate against your signal voltage and package requirements.
Switching times are 275ns max (turn-on) and 150ns max (turn-off). These are the maximums over the rated temperature range; typical performance is better.
The MAX349CAP+ is the ROHS3-compliant lead-free variant of the MAX349CAP. Electrical specifications – 8:1 mux, 100 Ohm on-resistance, 275ns/150ns switching, -90dB crosstalk – are identical. The + suffix indicates compliance with the ROHS3 directive. Package and footprint are the same 20-SSOP.
