LM2903WHYST STMicroelectronics

LM2903WH Low-power, dual-voltage comparator Datasheet - production data Features Wide, single supply voltage range or dual supplies, 2 V to 36 V or 1 V to 18 V Very low supply current (0.4 mA) independent of supply voltage (1 mW/comparator at 5 V) Low input bias current: 25 nA typ. Low input offset current: 5 nA typ. Input common-mode voltage range includes negative rail S Low output saturation voltage: 250 mV typ. MiniSO8 (I = 4 mA) O (plastic micropackage) Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible Pin connections (top view) outputs ESD internal protection: 2 kV Wide operating temperature range: -40 to 150 C Description This device consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. 1- Output 1 The input common-mode voltage range includes 2- Inverting input 1 negative rail even though operated from a single 3- Non-inverting input 1 - power supply voltage. 4 - V CC 5- Non-inverting input 2 All pins are protected against electrostatic 6- Inverting input 2 discharge up to 2 kV. Consequently, the input + - 7- Output 2 voltages must not exceed the V or V CC CC + 8 - V CC magnitudes.
