HMC675LC3C v10.0514 10 GHz LATCHED COMPARATORWITH RSCML OUTPUT STAGEPin Descriptions Pin Number Function Description Interface Schematic T 1 VTP Termination resistor return pin for Vp Input. M 2 INP Non-Inverting analog input 3 INN Inverting analog input 4 VTN Termination resistor return pin for Vn input S - S R 5, 16 Vcci Positive supply voltage input stage. O AT Latch enable bar input pin, inverting side. 6 LE Refer to the Operational Description for more details. R A P Latch enable input pin, non-inverting side. 7 LE Refer to the Operational Description for more details OM Pin is not connected inside the package. C 8 N/C Connect package pin to GND for improved noise. 9, 12 Vcco Positive supply voltage for the output stage. Inverting output. Q bar is at logic low if the analog voltage at the non-inverting input, INP, is greater than the analog 10 Q voltage at the inverting input, INN, provided that the comparator is in compare mode. Refer to the Operational Description for more details Non-inverting output. Q is at logic high if the analog voltage at the non-inverting input, INP, is greater than the analog 11 Q voltage at the inverting input, INN, provided that the comparator is in compare mode. Refer to the Operational Description for more details Hysteresis Control pin. This pin should be left disconnected for zero hysteresis. Connect to Vee with a resistor to add 14 HYS the desired amount of hysteresis. Refer to hysteresis graph to determine the correct sizing of Rhys control resistor. 13 Vee Negative power supply, -3V. 15 RTN Return for ESD protection. Package Base Exposed paddle must be connected to Vee.
