LTC1380/LTC1393

Single-Ended 8-Channel/

Differential 4-Channel Analog

Multiplexer with SMBus Interface

FEATURES

DESCRIPTION

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 10µA. Both digital interface

pins are SMBus compatible over the full operating supply

voltage range. The LTC1380 analog switches feature a

typical R

of 35Ω (±5V supplies), typical switch leakage of

20pA and guaranteed break-before-make operation. 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.
