Complementary Products for the TMS320™ DSP Family

Linear and Logic Products
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 of 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 nonover-voltage 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 I2C 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 VCC 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.
