8 x Digital Sensor Interface FZE 1658G Features q q q q q q Input protection against 2000 V burst/500 V surge pulse according to IEC 801 4/5 Input characteristic according to IEC 65 A, type 2 (24 V DC) Digital filter Serial in/out for easy cascading Low power dissipation SMD package P-DSO-24-1 Type FZE 1658G Ordering Code Q67000-A8361 Package P-DSO-24-1 The FZE 1658G is an integrated interface for digital sensors - i.e. proximity switches - in industrial automation equipment. The IC has eight integrated highly protected and failsafe inputs with status LED and a serial synchronous output for direct MC-interfacing. Semiconductor Group 1 01.97 FZE 1658G Pin Configuration (top view) Semiconductor Group 2 FZE 1658G Pin Definitions and Functions Pin 15, 13, 11, 9, 5, 3, 1, 23 16, 14, 12, 10, 6, 4, 2, 24 21 7 22 Symbol Function I0 - I7 L0 - L7 CT GND DGND Inputs for 24-V signals, in conjunction with RV and REXT current sink characteristic. Outputs for the status LEDs; LED lights when H-signal is present at input. Pin for connecting the frequency-determining capacitor for the filter clock; also reset input if CT is connected to DGND. Ground for all 24-V signals, substrate. Ground for all 5-V signals, no internal connection to GND. Any interruption of GND or DGND with the supply voltage present may result in destruction of the device. Supply voltage; undervoltage activates internal reset. Serial output, open drain. Extention input for serial cascading with pull-up cur...
