These parts are CMOS monolithic analog multiplexer/demultiplexers designed for use with signal frequencies ranging from DC through video. This part is a 2-of-8(4 Channel differential) multiplexer . A key feature of this part is extremely high off isolation at high frequencies. The isolation of each off channel to the output is guaranteed to be -66dB at 5MHz. The input signal range is +12V to -15V with ±15V power supplies while power con-sumption is typically 1.1mW. All control inputs are fully compatible with TTL and CMOS logic. Decoding is in standard BCD format and an Enable input is also provided to simplify cascading of devices. This part will operate with nearly any power supply combination which totals less than 36V (V+ – V-) including single supply operation at +12V, +15V, and +28V with V-connected to GND.
