There is a 28-LCC (J-Lead) that comes with the timer clock, which is enclosed in the packaging. This programmable timer has been set to 8MHz frequencies.It is used to pack in Tube case. The recommended mounting type is Surface Mount.It is possible to provide a voltage of 4.5V~5.5V by using the programmable timer.The type of chips can be divided into Programmable Timer. The operating temperature of this timer clock is -40°C~85°C. To keep the clock timer's supply current at 10mA. It is based on 82C54. The supply voltage of the programmable timer can rate 5V. The sum of the IC chip pins is 28 . The number of the chip's terminations sums up to 28.
