MM454
MM454 is four-channel commutator manufactured by National Semiconductor.
description The f Ii IM454/MM554 IS a four-channel analog mutator capable of switching four analog input channels sequentially onto an output line. The device is constructed on a single silicon chip using Ma S P Channel enhancement transistors; it contains all the digital cir CUitry 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 mutating Rate - Low Leakage Current (TA = 25° C) (TA = 85°C) ±10V 500 k Hz 200p A 50n A - 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...
