Die set.
Description of products
PR4537 is according to 1/4 unicolor display panels scanning of actual demand, a slice of 74HC245 on the board, 1 slice
74HC138, a 74HC123 and peripheral capacitance-resistance circuit, adopt the highly Integrated mode, its corresponding function design
Get to the circuit of the foot of film 20.
Within PR4537, the monostable protective circuit of integrating and 74HC123 functional equivalent, is expert at the decipher input signal
After A_IN stops jump transfer about 130ms, the monostable protective circuit will be in protecting state, will close the conduct decipher to export.
Within PR4537, has integrated two-way clock dashpot, No. one (CLK_OUT1) among them Used in this board, in addition
No. one (CLK_OUT0) Give output interface. The intersection of power-handling capability and 2 times as much as that of CLK_OUT0 of CLK_OUT1 among them
Within PR4537, have integrated two-wayly and latched the dashpot of signals, No. one (LD_OUT1) among them Used in this board, another
No. one (LD_OUT0) outside Give output interface
Within PR4537, reveal the dashpot of the enabling signal (OEB_OUT0) after integrating No. one Give output interface
Inside PR4537, integrate one No. transfer the intersection of intelligence signal and dashpot (SD_OUT) Count for the displacement of 74HC595
According to the input end
Inside PR4537, integrate two-way the intersection of line signal and dashpot, use after the buffer giving output interface, a built-in one at the same time
A 2-4 Decoders, output decoded signal (LINE0-LINE3) of 4 routes Used for controlling the conduct to drive the tube.
PR4537 is suitable for 1/4 of the scanning, adopts 74HC595 as the display screen die set listing the driver. At the same time, to inputting
Signal go on pulling upward or downstream pull,further peripheral to be simplify circuit design.
There is complete ESD protective circuit, ability to resist static> 2000V (HBM) within PR4537
