The is a single 8 channel low voltage analogue multiplexer in 16 pin TQFN package. This CMOS analogue multiplexer/demultiplexer operates from a single +1.8V to +5V supply or dual ±2.5V supplies. This device features 3.5ohm on-resistance RON when powered with a single +5V supply and have -75dB off-isolation and -85dB crosstalk from the output to each off channel. The switching times are 18ns tON and 7ns tOFF. It features a -3dB 85MHz bandwidth and has a 0.25nA leakage current at +25°C. A +1.8V to +5.5V operating range makes the device is ideal for battery-powered, portable instruments. All channels have break-before-make switching. This device feature bidirectional operation and can handle rail to rail analogue signals. All control inputs are TTL/CMOS logic compatible. Decoding is in standard BCD format and an enable input is provided to simplify cascading of devices.
