MAX14778ETP+T Description

Short technical summary and product information.

The MAX14778ETP+T is a dual 4:1 analog multiplexer designed by Analog Devices / Maxim Integrated. It supports analog signals up to ±25V with a single 3.0V to 5.5V supply, eliminating the need for a negative power supply. Each multiplexer has independent control inputs, making it suitable for multiplexing different communication signals. The device offers a low 1.5Ω (max) on-resistance and 3mΩ (typ) flatness, ensuring signal integrity.

 

This multiplexer can handle up to 300mA of continuous current and supports switching of full-speed USB 1.1 signals (12Mbps) and RS-485 data rates up to 20Mbps. It features extended ESD protection of ±6kV (Human Body Model) on the A_ and B_ pins, enabling direct interfacing to cables and connectors. The MAX14778ETP+T is specified for an industrial temperature range of -40°C to +125°C.

 

Applications include RS-485/RS-232/USB 1.1 multiplexing, POS peripherals, handheld industrial devices, communication systems, audio/data multiplexing, connector sharing, and gaming machines. The device is housed in a compact 20-pin (5mm x 5mm) TQFN package, suitable for surface mount applications.
