点击查看特定型号的库存状况。

说明

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, I2C-compatible serial interface. The MAX4573/MAX4574 feature a 3-wire, SPI™/QSPI™/MICROWIRE™-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.
