GENERAL DESCRIPTION The ADG774A is a monolithic CMOS device comprising four These switches conduct equally well in both directions when 2:1 multiplexer/demultiplexers with high impedance outputs. on. In the off condition, signal levels up to the supplies are The CMOS process provides low power dissipation yet offers blocked. The ADG774A switches exhibit break-before-make high switching speed and low on resistance. The on resistance switching action. variation is typically less than 0.5 over the input signal range. PRODUCT HIGHLIGHTS The bandwidth of the ADG774A is typically 400 MHz and this, 1. Wide bandwidth data rates of >400 MHz. coupled with low distortion (typically 0.3%), makes the part 2. Ultralow power dissipation. suitable for switching of high speed data signals. 3. Low leakage over temperature. The on resistance profile is very flat over the full analog input 4. Break-before-make switching prevents channel shorting range ensuring excellent linearity and low distortion. CMOS when the switches are configured as a multiplexer. construction ensures ultralow power dissipation. 5. Crosstalk is typically 70 dB 10 MHz. 6. Off isolation is typically 65 dB 10 MHz. The ADG774A operates from a single 3.3 V/5 V supply and is 7. Available in compact 3 mm 3 mm LFCSP. TTL logic-compatible. The control logic for each switch is shown in the truth table (see Table 5).
