Digital Logic Products for All TMS320™ DSP Platforms
Bus Interface Products
•The LVC and ALVC families offer Vcc fully specified to match the needs of the TMS320™ 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
Little Logic
•Ability to place a single gate in critical locations provides for simplified routing and board space savings
•Single gates also provide easy state change for control inputs
•The NanoStar package provides the industry’s smallest logic package
Level Translation
•Interface between a 3.3-V DSP and 5-V I/O modules
•Interface to 5-V CMOS-level devices which cannot be operated reliably from 3.3-V outputs
•Interface 5-V memory modules that must be connected to 3.3-V components
Bus Switches
•Support easy bus communication between devices (i.e., memory and DSP)
•Near-zero propagation delay enables highest system speed– tpd(MAX) = 0.25 ns for CBTLV
•Applications include: 5-V to 3-V translators, hot card insertion, portable equipment and wireless
I/O Expansion
•I2C to parallel port expander
•Compatible with most processors and microcontrollers
