APPLICATIONS RGB switches HDTV DVD-R Audio/video switches GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The ADG794 is a monolithic CMOS device comprising four 1. Wide bandwidth: 300 MHz. 2:1 multiplexers/demultiplexers with high impedance outputs. 2. Ultralow power dissipation. The CMOS process provides low power dissipation yet gives high 3. Crosstalk: 70 dB (typical) at 10 MHz. switching speed and low on resistance. The on-resistance variation is less than 1.2 over the input signal range. 4. Off isolation: 65 dB (typical) at 10 MHz. The wide bandwidth of the ADG794 (300 MHz typical), coupled 5. ESD protection tested as per ESD Association Standards: with low distortion (0.18% typical), makes the part suitable for 2 kV HBM (ANSI/ESD STM5.1-2001) switching analog audio/video signals. 200 V MM (ANSI/ESD STM5.2-1999) 1 kV FICDM (ANSI/ESD STM5.3.1-1999) The ADG794 operates from a single 3.3 V/5 V supply and is TTL logic compatible. The switches are controlled by the logic inputs IN and EN, as shown in Table 4. The EN pin allows the user to disable all switches. These switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked. The ADG794 switches exhibit break-before-make switching action. The ADG794 is available in a 16-lead QSOP. Rev.
