Dallas Texas Instruments (TI) has introduced a highly integrated digital-input serializer, which incorporates eight channels and flexible features to provide high-density signal conditioning in a single, compact device.
The SN65HVS882 serializer converts eight digital inputs, ranging from 0 V to 34 V, into a single data stream on SPI interface, which simplifies the design and saves overall board space for industrial automation and test and measurement equipment.
The SN65HVS882 integrates several key functions, which typically must be performed by external components. The high channel density and feature integration allow engineers to reduce overall board space up to 60 percent compared to competing products, according to TI.
Several SN65HVS882 eight-channel serializers can be cascaded through an integrated SPI port, reducing both the isolation channels and controller pins required for high channel-count input modules. In addition, the internal programmable de-bounce feature filters out spurious pulses up to 3 ms on noisy switch inputs, eliminating the need for external components or software. These capabilities help provide a more cost-efficient, high-density input system.
Pricing: $3 in 1,000-piece quantities.
Availability: Now from TI and its authorized distributors in a 28-pin HTSSOP package.
