SN65HVS880PWP

Сериализатор с цифровым входом, 8 входов, 1МБ/с, 18В до 30В, TSSOP-28.

The SN65HVS880PWP is a 8-input 24V Digital-input Serializer for industrial digital inputs. It is for high-channel density digital input modules of PC and PLC based systems in industrial automation. In combination with galvanic isolators the device completes the interface between the 24-V sensor outputs of the field-side and the low-voltage controller inputs at the control-side. Input signals provided by EN60947-5-2 compliant 2- and 3-wire proximity switches are current-limited and then validated by internal debounce filters. The input switching characteristic is in accordance with IEC61131-2 for Type 1, 2 and 3 sensor switches. 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. Input status is indicated via 3mA constant current LED outputs. An external precision resistor is required to set the internal reference current.
