tiplexers comprising eight single channels and four differential 1. Extended Signal Range channels respectively, fully specified for ± 5 V, +5 V and +3 V The ADG608/ADG609 are fabricated on an enhanced power supplies. The ADG608 switches one of eight inputs to a LC2MOS process giving an increased signal range which common output as determined by the 3-bit binary address lines extends to the supplies. A0, A1 and A2. The ADG609 switches one of four differential 2. Low Power Dissipation inputs to a common differential output as determined by the 2-bit binary address lines A0 and A1. An EN input on both de- 3. Low RON vices is used to enable or disable the device. When disabled, all 4. Fast Switching Times channels are switched OFF. All the address and enable inputs are TTL compatible over the full specified operating tempera- 5. Break-Before-Make Switching ture range, making the parts suitable for bus-controlled systems Switches are guaranteed break-before-make so that input such as data acquisition systems, process controls, avionics and signals are protected against momentary shorting. ATEs since the TTL compatible address inputs simplify the digital 6. Single/Dual Supply Operation interface design and reduce the board space requirements. The ADG608/ADG609 are designed on an enhanced LC2MOS
