Teilenummer : ADG774ABRQ
Function : 0.3-6V; 556mW; low voltage 400MHz quad 21 mux with 3ns switching time
Hersteller : Analog Devices
The ADG774A is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs. The CMOS process provides low power dissipation yet offers high switching speed and low on resistance. The on resistance variation 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 part suitable for switching of high speed data signals.
The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion. CMOS construction ensures ultralow power dissipation. The ADG774A operates from a single 3.3 V/5 V supply and is TTL logic-compatible. The control logic for each switch is
shown in the truth table (see Table 5).
