The HEF4543B is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED displays. It has four address inputs (D0 to D3), an active LOW latch enable input (LE), an active HIGH blanking input ...

The 74HC(T)4511 is a BCD to 7-segment latch/decoder/driver that features latch storage of BCD inputs, blanking input, lamp test input, a driving common cathode LED displays, 10 mA drive capability per ...

Abstract: Now-a-days majority of practical applications such as valet car parking, larger temples necessitate, seven segment displays to give a visual token of the numbers. Digital counters are the ...
