Overview
19-5929; Rev 1; 6/12 EVALUATION KIT AVAILABLE MAX14778 Dual ±25V Above- and Below-the-Rails 4:1 Analog Multiplexer General Description The MAX14778 dual 4:1 analog multiplexer supports analog signals up to Q25V with a single 3.
0 to 5.
5V supply.
Each multiplexer has separate control inputs to allow independent switching, making the device ideal for multiplexing different communications signals with the same connector pins.
Extended ESD protection of Q6kV (Human Body Model) enable direct interfacing to cables and connectors.
The MAX14778 features a low 1.
5I (max) on-resistance and 3mI (typ) flatness to maximize signal integrity over the entire common-mode voltage range.
Each multiplexer can carry up to 300mA of continuous current through the multiplexer in either direction.
The MAX14778 supports switching of full-speed USB 1.
1 signals (12Mbps) and RS-485 data rates of up to 20Mbps.
The MAX14778 is available in a 20-pin (5mm x 5mm) TQFN package and is specified over the -40NC to +85NC extended temperature range.
