TMP82C54

      The TMP82C54P-2 TMP82C54M-2 (hereafter called the TMP82C54) is a low power CMOS general-purpose programmable timer/counter.
      Here you can get some information about some features.First,The pin is compatible with the TMP82C53P-2 (TMP82C54P-2).Secondly,it consists of 3 independent 16-bit counters to implement high-speed counting.Thirdly,the count data read is available.Fourthly,the status read is available.Fifthly,it contains six programmable counter modes.Sixthly,it has binary/decimal count selection.Seventhly,it has high speed operation.The clock input can be up to 10 MHz.The eighth one is that it has low power dissipation which is 300 mA max. in operation and 10 A max.The ninth one is that TMP8253P-5 has extended operating temperature which is from -40 to 85.The last one is that the power supply voltage is 5V±10%.
      What comes next is about the TMP8253P-5 maximum ratings.The V_CC (supply voltage) is from -0.5 to +7.0 V.The V_IN (input voltage) is from -0.5 to V_CC+0.5 V.The V_OUT (output voltage) is from -0.5 to V_CC+0.5 V.The P_D (power dissipation) is 250 mW.The Tsol (solder temperature) is 260 (10 sec) .The Tstg (storage temperature) is from -65 to 150.The Topr (operating temperature) is from -40 to +85.
