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 FZE 1658G Pin Configuration (top view) Semiconductor Group 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 current source. Latch input, edge H-L results in transfer of data from the digital filters to the output register. Clock for serial output, positive edge triggered. 8 20 17 18 19 SO-N SE-N LO-N Semiconductor Group FZE 1658G Functional Description and Application The Integrated circuit FZE 1658G is used to detect the signal states of eight independent input lines according to IEC 65A Type 2 (e.g. two-wire proximity switches) with a mon ground (GND). For operation in accordance with IEC 65A, it is necessary for the device to...
