3 / 6 page 3 www.fairchildsemi.com Absolute Maximum Ratings(Note 3) Note 3: 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 tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. DM74LS155 Recommended Operating Conditions DM74LS155 Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Note 4: All typicals are at VCC = 5V, TA = 25° C. Note 5: Not more than one output should be shorted at a time, and the duration should not exceed one second. Note 6: ICC is measured with all outputs OPEN, A,B, and C1 inputs at 4.5V, and C2, G1, and G2 inputs GROUNDED. DM74LS155 Switching Characteristics at VCC = 5V and TA = 25°C Supply Voltage 7V Input Voltage 7V Operating Free Air Temperature Range 0 °C to +70°C Storage Temperature Range −65°C to +150°C Symbol Parameter Min Nom Max Units VCC Supply Voltage 4.75 5 5.25 V VIH HIGH Level Input Voltage 2 V VIL LOW Level Input Voltage 0.8 V VOH HIGH Level Output Current −0.4 mA IOL LOW Level Output Current 8 mA TA Free Air Operating Temperature 0 70 °C Symbol Parameter Conditions Min Typ Max Units (Note 4) VI Input Clamp Voltage VCC = Min, II = −18 mA −1.5 V VOH HIGH Level VCC = Min, IOH = Max 2.7 3.4 V Output Voltage VIL = Max, VIH = Min VOL LOW Level VCC = Min, IOL = Max 0.35 0.5 Output Voltage VIL = Max, VIH = Min V IOL = 4 mA, VCC = Min 0.25 0.4 II Input Current @ Max Input Voltage VCC = Max, VI = 7V 0.1 mA IIH HIGH Level Input Current VCC = Max, VI = 2.7V 20 µA IIL LOW Level Input Current VCC = Max, VI = 0.4V −0.36 mA IOS Short Circuit Output Current VCC = Max (Note 5) −20 −100 mA ICC Supply Current VCC = Max (Note 6) 6.1 10 mA From (Input) RL = 2 kΩ Symbol Parameter To (Output) CL = 15 pF CL = 50 pF Units Min Max Min Max tPLH Propagation Delay Time A, B, C2, G1 18 22 ns LOW-to-HIGH Level Output or G2 to Y tPHL Propagation Delay Time A, B, C2, G1 27 35 ns HIGH-to-LOW Level Output or G2 to Y tPLH Propagation Delay Time A or B 18 24 ns LOW-to-HIGH Level Output to Y tPHL Propagation Delay Time A or B 27 35 ns HIGH-to-LOW Level Output to Y tPLH Propagation Delay Time C1 20 24 ns LOW-to-HIGH Level Output to Y tPHL Propagation Delay Time C1 27 35 ns HIGH-to-LOW Level Output to Y |
