General Description

The fIiIM454/MM554 IS a four-channel analog commutator capable of switching four analog input channels sequentially onto an output line.

The device is constructed on a single silicon chip using MaS P Channel enhancement transistors;

it contains all the digital cirCUitry necessary to sequentially turn ON the four analog switch transistors permitting multiplexing of the analog input data.

Overview

Analog Switches MM454/MM554 four-channel commutator general.

Key Features

High Analog Voltage Handling.
High Commutating Rate.
Low Leakage Current (TA = 25° C) (TA = 85°C) ±10V 500 kHz 200pA 50nA.
All Channel Blanking input provided.
Reset capability provided.
Low ON Resistance 200n In addition, the MM454/MM554 can easily be applied where submultiplexing is required since a 4: 1 clock countdown signal is provided which can drive the clock input of subsequent MM454/MM554 units. The MM454 is specified for ope.
