TThe ADG774A is a monolithic CMOS device comprising four2:1 multiplexer/demultiplexers with high impedance outputs.The CMOS process provides low power dissipation yet offershigh switching speed and low on resistance. The on resistancevariation is typically less than 0.5 Ω over the input signal range.The bandwidth of the ADG774A is typically 400 MHz and this,coupled with low distortion (typically 0.3%), makes the partsuitable for switching of high speed data signals.The on resistance profile is very flat over the full analog inputrange ensuring excellent linearity and low distortion. CMOSconstruction ensures ultralow power dissipation.The ADG774A operates from a single 3.3 V/5 V supply and isTTL logic-compatible. The control logic for each switch isshown in the truth table.These switches conduct equally well in both directions whenon. In the off condition, signal levels up to the supplies areblocked. The ADG774A switches exhibit break-before-makeswitching action. Product Highlights Wide bandwidth data rates of >400 MHz. Ultralow power dissipation. Low leakage over temperature. Break-before-make switching prevents channel shorting when the switches are configured as a multiplexer. Crosstalk is typically −70 dB @ 10 MHz. Off isolation is typically −65 dB @ 10 MHz. Available in compact 3 mm × 3 mm LFCSP.
