SCL is the synchronizing clock generated by the host. SDA
is the bidirectional data transfer between the host and the
slave. The host initiates a start bit by dropping the SDA line
from High to Low while the SCL is High. The stop bit is
initiated by changing the SDA line from Low to High while
SCL is High. All address, command and acknowledge
signals must be valid and should not change while SCL is
High. The acknowledge bit signals to the host the accep-
tance of a correct address byte or the command byte.
At V
CC
supply above 2.7V, the SCL and SDA input thresh-
old is typically 1V with an input hysteresis of 100mV. The
typical SCL and SDA lines have either a resistive or current
source pull-up at the host. The LTC1380/LTC1393 have an
open-drain NMOS transistor at the SDA pin to sink 3mA
below 0.4V during the slave acknowledge sequence. The
address selection input A1 and A0 are TTL compatible at
V
CC
= 5V.
Both the LTC1380 and LTC1393 are compatible with the
Philips/Signetics I
2
C Bus interface. This 1V threshold for
SCA and SDA should not pose an operational problem
with I
2
C applications.
The multiplexer switches are selected as shown in Table 2.
Both the LTC1380 and the LTC1393 have an enable bit
(EN). A Low disables all switches while a High enables the
selected switch as programmed by bits C2, C1 and C0. A
stop bit after a successful send byte sequence for LTC1380/
LTC1393 will disable all switches before the new selected
switch is connected.
