DM74LS136 Quad 2-Input Exclusive-OR Gate with Open-Collector Outputs February 1992 Absolute Maximum Ratings (Note) Supply Voltage Note: The ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the ‘‘Electrical Characteristics’’ table are not guaranteed at the absolute maximum ratings. The ‘‘Recommended Operating Conditions’’ table will define the conditions for actual device operation. 7V Input Voltage Operating Free Air Temperature Range Storage Temperature Range 7V 0§ C to a 70§ C b 65§ C to a 150§ C Recommended Operating Conditions Symbol Parameter VCC Supply Voltage VIH High Level Input Voltage VIL Low Level Input Voltage IOL Low Level Output Current TA Free Air Operating Temperature Min Nom Max Units 4.75 5 5.25 V 2 V 0 0.8 V 8 mA 70 §C Electrical Characteristics Over recommended operating free air temperature range (unless otherwise noted) Symbol Parameter Conditions Min Typ (Note 1) Max VI Input Clamp Voltage VCC e Min, II e b18 mA ICEX High Level Output Current VCC e Min, VO e 5.5V VOL Low Level Output Voltage VCC e Min, IOL e Max VIH e Min 0.35 0.5 IOL e 4 mA, VCC e Min 0.25 0.4 II Input Current @ Max Input Voltage VCC e Max, VI e 7V IIH High Level Input Current IIL ICC Units b 1.5 V 100 mA V 0.2 mA VCC e Max, VI e 2.7V 40 mA Low Level Input Current VCC e Max, VI e 0.4V b 0.6 mA Supply Current VCC e Max 10 mA Note 1: All typicals are at VCC e 5V, TA e 25§ C.
