LM393Y

The LM393Y consists of two independent voltage comparators that are designed to operate from a single power sup ply over a wide variety of voltages.Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Curre nt drain is independent of the supply voltage. The outputs is able to be combined to other open-collector outputs to achieve wired-AND relationships.

Features of LM393Y are: (1)single supply or dual supplies; (2)wide range of supply voltage: 2 V to 36 V; (3)low supp ly-current drain independent of supply voltage:0.4 mA typ per comparator; (4)low input bias current: 25 nA Typ; (5)low input offset voltage: 2 mV Typ; (6)common-mode input voltage range includes ground; (7)differential input volt age range equal tomaximum-rated Supply voltage: ±36 V; (8)low output saturation voltage; (9)output compatible with TTL, MOS, and CMOS.

The absolute maximum ratings of the LM393Y can be summarized as: (1)supply voltage: 36V; (2)differential input voltage:±36 V; (3)input voltage range:0.3V to 36V; (4)output voltage: 36V; (5)output current: 20 mA; (6)duration of output short-circuit to ground: unlimited; (7)package thermal impedance, qJA(D package): 97°C/W; (8)lead temp erature 1,6 mm (1/16 inch) from case for 60 seconds(JG package): 300°C; (9)storage temperature range65°C to 150°C, etc.
