The ADG658 and ADG659 are low voltage， CMOS analog multiplexers comprised of eight single channels and four differential channels， respectively. The ADG658 switches one of eight inputs （S1–S8） to a common output， D， as determined by the 3-bit binary address lines A0， A1， and A2. The ADG659 switches one of four differential inputs to a common differential output， as determined by the 2-bit binary address lines A0 and A1. An EN input on both devices enables or disables the device. When disabled， all channels are switched off. These devices are designed on an enhanced process that provides lower power dissipation yet gives high switching speeds. These devices can operate equally well as either multiplexers or demultiplexers and have an input range that extends to the supplies. All channels exhibit break-before-make switching action， preventing momentary shorting when switching channels. All digital inputs have 0.8 V to 2.4 V logic thresholds， ensuring TTL/CMOS logic compatibility when using single +5 V or dual ±5 V supplies. The ADG658 and ADG659 are available in 16-lead TSSOP/ QSOP packages and 16-lead 4 mm × 4 mm LFCSP packages.
