DATA SHEET www.onsemi.com Universal Voltage Monitors MARKING DIAGRAMS MC34161, MC33161, NCV33161 8 MC3x161P PDIP8 The MC34161/MC33161 are universal voltage monitors intended AWL P SUFFIX for use in a wide variety of voltage sensing applications. These devices YYWWG CASE 626 offer the circuit designer an economical solution for positive and 1 negative voltage detection. The circuit consists of two comparator 1 channels each with hysteresis, a unique Mode Select Input for channel 8 programming, a pinned out 2.54 V reference, and two open collector SOIC8 3x161 outputs capable of sinking in excess of 10 mA. Each comparator D SUFFIX ALYW channel can be configured as either inverting or noninverting by the CASE 751 1 Mode Select Input. This allows over, under, and window detection of 1 positive and negative voltages. The minimum supply voltage needed for these devices to be fully functional is 2.0 V for positive voltage 8 sensing and 4.0 V for negative voltage sensing. Micro8 x161 Applications include direct monitoring of positive and negative DM SUFFIX AYW voltages used in appliance, automotive, consumer, and industrial CASE 846A equipment. 1 1 Features x = 3 or 4 Unique Mode Select Input Allows Channel Programming A = Assembly Location Over, Under, and Window Voltage Detection WL, L = Wafer Lot Positive and Negative Voltage Detection YY, Y = Year WW, W = Work Week Fully Functional at 2.0 V for Positive Voltage Sensing and 4.0 V G or = PbFree Package for Negative Voltage Sensing (Note: Microdot may be in either location) Pinned Out 2.54 V Reference with Current Limit Protection Low Standby Current Open Collector Outputs for Enhanced Device Flexibility PIN CONNECTIONS NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements AECQ100 V 1 8 V ref CC Qualified and PPAP Capable Input 1 Mode Select 2 7 These Devices are PbFree and are RoHS Compliant Input 2 3 6 Output 1 8 GND 4 5 Output 2 1 (TOP VIEW) 2.54 V Reference V S 7 ORDERING INFORMATION - + + 6 See detailed ordering and shipping information in the package 2 2.8 V dimensions section on page 15 of this data sheet. + + - 1.27 V - + 5 + 3 0.6 V + + - 1.27 V 4 This device contains 141 transistors.
