The MAX454CPD is a dual, low-power, high-speed, CMOS analog multiplexer/demultiplexer manufactured by Maxim Integrated. It is a 14-pin DIP package.

Description:
The MAX454CPD is a dual, low-power, high-speed, CMOS analog multiplexer/demultiplexer. It is designed to provide high-speed switching of two analog signals. It has two independent, single-pole/double-throw (SPDT) switches with a common control signal. The device is designed to operate from a single +5V power supply.

Features:
Low power consumption (1.2 mW max)
High speed switching (tpd = 35 ns max)
Low on-resistance (RON = 0.5 Ω max)
TTL/CMOS compatible control logic
Low crosstalk (–60 dB max)
Low distortion (–60 dB max)
Low leakage current (0.1 nA max)
High off-isolation (–90 dB min)

Applications:
The MAX454CPD is suitable for a wide range of applications, including signal routing, signal switching, and signal conditioning. It can be used in audio, video, and telecommunications systems. It is also suitable for use in medical instrumentation, test and measurement equipment, and instrumentation amplifiers.
