MM454

Analog Switches MM454/MM554 four-channel commutator 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. The device 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 operation over the -55°C to +125°C military tempe...
