LM393DR

LM193, LM293, LM393 Low-power, dual-voltage comparators Datasheet - production data Description The LM193, LM293, and LM393 devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage. Features Wide single-supply voltage range or dual supplies: 2 V to 36 V or ±1 V to ±18 V Very low supply current (0.45 mA) independent of supply voltage (1 mW/comparator at 5 V) Low input bias current: 20 nA typ. Low input offset current: ±3 nA typ. Low input offset voltage: ±1 mV typ. Input common-mode voltage range includes ground Low output saturation voltage: 80 mV typ. (Isink = 4 mA) Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible outputs Available in DFN8 2x2, MiniSO8, TSSOP8, and SO8 packages February 2016 DocID2164 Rev 15 This is information on a product in full production. 1/21 www.st.com Contents LM193, LM293, LM393 Contents 1 Schematic diagram.......................................................................... 3 2 Package pin connections................................................................ 4 3 4 Absolute maximum ratings and operating conditions ................. 5 Electrical characteristics ................................................................ 7 5 Electrical characteristic curves ...................................................... 8 6 Typical applications ........................................................................ 9 7 Package information ..................................................................... 12 7.1 DFN8 2x2 package information ....................................................... 13 7.2 MiniSO8 package information ......................................................... 15 7.3 TSSOP8 package information ......................................................... 16 7.4 SO8 package information ................................................................ 17 8 Ordering information..................................................................... 18 9 Revision history ............................................................................ 19 2/21 DocID2164 Rev 15 LM193, LM293, LM393 1 Schematic diagram Schematic diagram Figure 1: Schematic diagram (1/2 LM193) DocID2164 Rev 15 3/21 Package pin connections 2 LM193, LM293, LM393 Package pin connections Figure 2: Pin connections (top view) 1. 4/21 The exposed pad of the DFN8 2x2 can be left floating or connected to ground DocID2164 Rev 15 LM193, LM293, LM393 3 Absolute maximum ratings and operating conditions Absolute maximum ratings and operating conditions Table 1: Absolute maximum ratings Symbol Parameter VCC Supply voltage Vid Differential input voltage Vin Input voltage ±36 Thermal resistance junction to case Tj (2) (2) DFN8 2x2 57 MiniSO8 190 TSSOP8 120 SO8 125 DFN8 2x2 — MiniSO8 39 TSSOP8 37 SO8 40 Storage temperature range HBM: human body model ESD class Infinite Maximum junction temperature Tstg (3) MM: machine model V -0.3 to 36 (1) Thermal resistance junction to ambient Rthjc Unit ±18 or 36 Output short-circuit to ground Rthja Value 150 -65 to 150 (4) °C/W °C H1B (5) M2 CDM: charged device model (6) C5 Notes: (1) Short-circuits from the output to VCC+ can cause excessive heating and potential destruction.

(2) The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines. (3) Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3 V (or 0.3 V below the negative power supply, if used). (4) The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals, 300 ns can be obtained.
