I2C, 8-Channel Gamma Buffer with EEPROM

byte before terminating the transaction. After the master
reads the last byte it must NACK to indicate the end of
the transfer and generates a STOP condition.
Manipulating the address counter for reads: A
dummy write cycle can be used to force the address
counter to a particular value. To do this the master gen-
erates a START condition, writes the slave address
byte (R/W = 0), writes the memory address where it
desires to read, generates a repeated START condi-
tion, writes the slave address byte (R/W = 1), reads
data with ACK or NACK as applicable, and generates a
STOP condition. The master must NACK the last byte to
inform the slave that no additional bytes are to be read.
Applications Information
Power-Supply Decoupling
To achieve the best results when using the DS3508,
decouple both power-supply pins (VCC and VDD) with a
0.01F or 0.1F capacitor. Use a high-quality ceramic
surface-mount capacitor if possible. Surface-mount
components minimize lead inductance, which improves
performance, and ceramic capacitors tend to have
adequate high-frequency response for decoupling
applications.
SDA and SCL Pullup Resistors
SDA is an I/O with an open-collector output that
requires a pullup resistor to realize high-logic levels. A
master using either an open-collector output with a
pullup resistor or a push-pull output driver can be used
for SCL. Pullup resistor values should be chosen to
ensure that the rise and fall times listed in the electrical
characteristics are within specification. A typical value
for the pullup resistors is 4.7k
惟.
