模拟多路复用器/解复用器, 3:1, 2电路, 0.75 ohm, 1.8V至5.5V电源, TDFN-14

The from Products is a dual 3:1 click less audio multiplexer with negative signal handling in 14 pin TDFN package. This dual 3:1 click less audio multiplexer features negative signal capability that allows signals as low as VCC - 5.5V to pass through without distortion. This multiplexer have a low on-resistance 0.38ohm, low supply current and operate from a single supply. It uses two digital control inputs CB1 and CB2 to switch between signals. The digital control inputs can accept up to +5.5V independent of the supply voltage. It is typically used in cell phones, PDAs and handheld devices, notebook computers and MP3 players.
