4543 CMOS BCD-7段译码-锁存-液晶驱动器
The tabular form of a BCD to 7-segment decoder with a common cathode display is shown below. The truth table consists of seven o/p columns equivalent to each of the seven segments. For example, the column for a-segment illustrates the various arrangements for which it is to be light up....
The CD4511BE is a CMOS BCD to 7 segment LED latch decoder driver in 16 pin DIP package. It is constructed with CMOS logic and NPN bipolar transistor output devices on a single monolithic structure. This device combines low ...
The basic decoder function (coding 4 input BCD lines to 7 output lines for LED display) was extended to an atypical function, protection of proper driving a 4-digit, 7-segment LED display. A special attention was paid to the circuit simplicity, use of the minimum number of devices and ...
