TIBPAL 16L8-20M

      TIBPAL 16L8-20M  is a kind of programmable array logic device.TIBPAL 16L8-20M has five features.The first one is that it has high-performance operation.The  maximum propagation delay is 20 ns.Secondly,it features functional equivalency and faster than PAL16L8A, PAL16R4A, PAL16R6A, and PAL16R8A.The third one is that it is a power-up clear on registered device (All register outputs are set high, but voltage levels at the output pins go low).At last,The package options include both plastic and ceramic chip carriers in addition to plastic and ceramic DIPs.

      What comes next is about the absolute maximum ratings of TIBPAL 16L8-20M over operating free-air temperature range.The supply voltage (V_CC) is 7 V.The input voltage is 5.5 V.The voltage applied to disabled output is 5.5 V.The operating free-air temperature range is from -55 to 125.The storage temperature range (T_stg) is from 65°C to 150.Then is about the recommended operating conditions.The minimum supply voltage (V_CC) is 4.5 V,the typical is 5 V and the maximum is 5.5 V.The minimum high-level input voltage (V_IH) is 2 V and the maximum is 5.5 V.The maximum low-level input voltage (V_IL) is 0.8 V.The maximum high-level output current (I_OH) is -2 mA.The maximum low-level output current (I_OL) is 12 mA.The minimum clock frequency (f_clock) is 0 MHz and the maximum is 41.6 MHz.The following is about the electrical characteristics over recommended operating free-air temperature range.The maximum V_IK is -1.5 V at V_CC = 4.5 V, II =-18 mA.The minimum V_OH is 2.4 V and the typical is 3.2 V at V_CC = 4.5 V, I_OH =-2 mA.The typical V_OL is 0.25 V and the maximum is 0.4 V at V_CC = 4.5 V, I_OL = 12 mA.The maximum I_I is 0.2 mA for pin 1,11 and 0.1 mA for all others at V_CC = 5.5 V, V_I = 5.5 V.The maximum IIH is 50A for pin 1,11,100A for I/O ports and 20A for all others at V_CC=5.5 V,V_I=2.7 V.The maximum I_IL is -0.25 mA for I/O ports and -0.2 mA for all others at V_CC=5.5 V,V_I=0.4 V.
