SN65HVS883 Datasheet | Texas Instruments

Features - 1 Eight Sensor Inputs - High Input Voltage up to 34 V - Selectable Debounce Filters From 0 ms to 3 ms - Adjustable Current Limits From 0.2 m A to 5.2 m A - Field Inputs and Supply Lines Protected to 15-k V HBM - Output Drivers for External Status LEDs - Cascadable for More Inputs in Multiples of Eight - SPI-patible Interface - Regulated 5-V Output for External Digital Isolator - Low-Supply Voltage Indicator 2 Applications - Sensor Inputs for Industrial Automation and Process Control - IEC61131-2 Type 1, 2, or 3 Switches - EN60947-5-2 Proximity Switches - High Channel Count Digital Input Modules for PC and PLC Systems - Decentralized I/O Modules Upon the application of load and clock signals, input data is latched in parallel into the shift register and afterwards clocked out serially via a subsequent isolator into a serial PLC input. Cascading of multiple SN65HVS883 is possible by connecting the serial output of the leading device with the serial input of the following device, enabling the design of high-channel count input modules. Input status is indicated via 3-m A constant current LED outputs. An external precision resistor is required to set the internal reference current. The integrated voltage regulator provides a 5-V output to supply lowpower isolators. An internal supply voltage monitor provides a chip-okay (CHOK) indication. The SN65HVS883 es in a 28-pin PWP Power PAD™ package allowing for efficient heat dissipation. The device is specified for operation at temperatures from - 40°C to 85°C.
