Communication systems Signal routing GENERAL DESCRIPTION
The ADG1308 and ADG1309 are monolithic analog multi- Fast switching speed coupled with high signal bandwidth makes plexers consisting of eight single channels and four differential the parts suitable for video signal switching. CMOS channels, respectively. The ADG1308 switches one of eight construction ensures ultra low power dissipation, making the inputs to a common output as determined by the 3-bit binary parts ideally suited for portable and battery-powered address lines A0, A1, and A2. The ADG1309 switches one of instruments. 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 is used to enable or disable the device. 1. 16-lead TSSOP and 16-lead SOIC_N available. When disabled, all channels are switched off. 2. Pin compatible with the ADG508AKR and the ADG509AKR devices. When the switches are on, each switch conducts equally well in both directions and has an input signal range that extends to 3. 3 V, logic-compatible digital input where: the power supplies. In the off condition, signal levels up to the VIH = 2.0 V and VIL = 0.8 V. supplies are blocked. All switches exhibit break-before-make 4. VL logic power supply not required. switching action for use in multiplexer applications. Inherent in 5. Low power consumption. the design is the low charge injection for minimum transients when switching the digital inputs.
