THRESHOLD SUFFIX SELECTOR DESCRIPTION Nominal Threshold Voltage Threshold Suffix Designation 4.63 V L 4.38 V M 4.00 V J 3.08 V T 2.93 V S 2.63 V R 2.32 V Z Table 2. PIN DESCRIPTION Pin Number Pin Name Description CAT811 CAT812 1 1 GND Ground. 2 − RESET Active LOW reset. RESET is asserted if VCC falls below the reset threshold and re- mains low for at least 140 ms after VCC rises above the reset threshold. − 2 RESET Active HIGH reset. RESET is asserted if VCC falls below the reset threshold and re- mains high for at least 140 ms after VCC rises above the reset threshold. 3 3 MR Manual Reset Input. A logic LOW on MR asserts RESET. RESET remains active as long as MR is LOW and for 140 ms after MR returns HIGH. The active low input has an internal 20 kW pull−up resistor. The input should be left open if not used. 4 4 VCC Power supply voltage that is monitored. Figure 1.
