LTC1380 Single-Ended 8-Channel Multiplexer
TYPICAL APPLICATION
U
The LTC
1380/LTC1393 are CMOS analog multiplexers with
SMBus
compatible digital interfaces. The LTC1380 is a
single-ended 8-channel multiplexer, while the LTC1393 is a
differential 4-channel multiplexer. The SMBus digital inter-
face requires only two wires (SCL and SDA). Both the
LTC1380 and the LTC1393 have four hard-wired SMBus
addresses, selectable with two external address pins. This
allows four devices, each with a unique SMBus address, to
coexist on one system and for four devices to be synchro-
nized with one stop bit.
The supply current is typically 10
A. Both digital interface
pins are SMBus compatible over the full operating supply
voltage range. The LTC1380 analog switches feature a
typical RON of 35 (±5V supplies), typical switch leakage of
20pAandguaranteedbreak-before-makeoperation.Charge
injection is
±1pC typical.
The LTC1380/LTC1393 are available in 16-lead SO and GN
packages. Operation is fully specified over the commercial
and industrial temperature ranges.
