They offer the designer an economical, space efficient solution for low supply voltage detection when used in combination with a single pull-up resistor. Adding one capacitor offers the functionality of a programmable delay time after power KEY FEATURES s Monitors +3.3V Supplies (V T = 2.7V Typ) s Outputs Fully Defined At V IN ≥ ≥≥≥≥ 1V (See Product Highlight) s Ultra-Low Supply Current (13µA Max.) ! Temperature Compensated I CC For Extremely Stable Current Consumption ! µP Reset Delay Programmable With 1 External Resistor And Capacitor ! Comparator Hysteresis Prevents Output Oscillation (60mV Typ.) ! Electrically Compatible With Motorola MC34164-3 ! Pin-to-Pin Compatible With Motorola MC34064 / MC34164 Note: All surface-mount packages are available in Tape & Reel. Append the letter "T" to part number. (i.e. MC34164-3DMT) returns. The MC33164-3 and MC34164-3 consist of a temperature stable reference comparator with hysteresis, high-current clamping diode and an open collector output stage capable of sinking more than 6mA over the full temperature range. The MC33164-3 and MC34164-3's RESET output is specified to be fully functional at V IN ≥ 1V. See Product Highlight below. PRODUCT HIGHLIGHT RESET OUTPUT VS.
