Datasheet Maxim MAX4574CEI — 数据表

19-1404; Rev 1; 4/99 Serially Controlled, Clickless
Audio/Video Switches
The MAX4571-MAX4574 serial-interface controlled
switches are ideal for multimedia applications. Each
device features 35Ω max on-resistance, -90dB audio
off-isolation at 20kHz, -60dB video off-isolation at
1.0MHz, and "clickless" mode operation for audio
applications.
The MAX4571/MAX4573 contain eleven SPST switches,
while the MAX4572/MAX4574 contain two SPST switches and six SPDT switches. The MAX4571/MAX4572 feature a 2-wire, I 2C^TM-compatible serial interface. The
MAX4573/MAX4574 feature a 3-wire, SPI^TM/QSPI^TM/
MICROWIRE^TM-compatible serial interface. All four
parts are available in 28-pin QSOP, SSOP, and wide
SO packages and operate over the commercial and
extended temperature ranges. Features
