Analog Switch
• Provide a high-speed bidirectional
bus interface between DSPs, CPUs,
industry standard buses, memory
and peripherals.
• TI’s analog switches are designed
to pass (or isolate) analog signals
(both voltage and current) and support
analog applications such as
audio and video data transmission.
• TI’s TS product family encompasses
a variety analog switches with different
ON resistances, bandwidth,
charge injection, and total harmonic
distortion to target any application.
Voltage Level Translation
• Interfacing any low-voltage component
with legacy, high-voltage devices
• Protects a DSP that has non-overvoltage
tolerant inputs.
• These dual-supply devices allow for
bidirectional level translation between
different voltage nodes from
1.2 V to 3.6 V and 1.65 V to 5.5 V.
I/O Expansion
• TI’s I 2 C I/O expanders allow system
layout to be greatly simplified.
• Two-wire bus reduces PCB complexity
through trace reduction and
routing simplification.
Bus Interface Products
• The LVC and ALVC families offer
V CC fully specified to match the
needs of the TMS320 DSP family:
3.3 V, 2.5 V and 1.8 V.
• Broad range of surface mount packaging
options from SOIC to BGA.
• Propagation delays of 3 ns and
below.
• Bus hold on data inputs decreases
system component count by eliminating
the need for external pull-up/
pull-down resistors.
