(16 pages)
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 switch-
es and six SPDT switches. The MAX4571/MAX4572 fea-
ture a 2-wire, I
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.
