unsuccessful data transfers. An unsuccessful data trans-
fer happens if a receiving device is busy or if a system
fault has occurred. In the event of an unsuccessful data
transfer, the bus master reattempts communication at a
later time.
The MAX1363/MAX1364 have a 7-bit I
address. The slave address is selected using A0. The
MAX1363/MAX1364 (EUB, MEUB, and LEUB) have
three base address options, allowing up to six devices
concurrently per I
The MAX1363/MAX1364 continuously wait for a START
condition followed by its slave address. When the device
recognizes its slave address, it is ready to accept or
send data depending on the R/W bit (Figure 6).

At power-up, the MAX1363/MAX1364 bus timing is set
for fast mode (F/S mode, up to 400kHz I
limits the conversion rate to approximately 22ksps.
Switch to high-speed mode (HS mode, up to 1.7MHz
I
The MAX1363/MAX1364 convert up to 133ksps in moni-
tor mode, regardless of I

Select HS mode by addressing all devices on the bus
with the HS-mode master code 0000 1XXX (X = don’t
care). After successfully receiving the HS-mode master
code, the MAX1363/MAX1364 issue a NACK, allowing
SDA to be pulled high for one clock cycle (Figure 7).
After the NACK, the MAX1363/MAX1364 operate in HS
mode. Send a repeated START (Sr) followed by a slave
address to initiate HS-mode communication. If the mas-
ter generates a STOP condition, the MAX1363/
MAX1364 return to F/S mode. Use a repeated START
condition (Sr) in place of a STOP condition to leave the
bus active and the mode unchanged.
