MAX4508CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4508CPE+ is a single 8-to-1 fault-protected multiplexer housed in a 16-pin Plastic DIP package. It operates with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. The device features ±40V overvoltage protection when power is off and ±25V protection when supplies are active. Key electrical parameters include a maximum on-resistance of 400 Ω, an on-resistance match between channels of 15 Ω max, and a fault output clamp turn-on delay of 20 ns. Logic inputs are TTL/CMOS compatible.
