DATA SHEET .onsemi. BCD-to-Seven Segment Latch/Decoder/Driver The MC14511B BCD- to- seven segment latch/decoder/driver is constructed with plementary MOS (CMOS) enhancement mode devices and NPN bipolar output drivers in a single monolithic structure. The circuit provides the functions of a 4- bit storage latch, an 8421 BCD- to- seven segment decoder, and an output drive capability. Lamp test (LT), blanking (BI), and latch enable (LE) inputs are used to test the display, to turn- off or pulse modulate the brightness of the display, and to store a BCD code, respectively. It can be used with seven- segment light- emitting diodes (LED), incandescent, fluorescent, gas discharge, or...
