The MC14511B BCD-7 segment latch/decoder/driver is constructed using a complementary MOS (CMOS) enhancement mode device and an NPN double-click output driver in a monolithic structure. The circuit provides 4-bit memory latch, 8421 BCD-7 segment decoder, and output driver functionality. The lamp test (LTbar), interval (BIbar), and latch enable (LE) inputs are used to test the display, turn off or pulse-modulate the brightness of the display, and store BCD codes, respectively. It can also be used directly or indirectly for seven-segment light-emitting diode (LED), incandescent, fluorescent, gas emission, or liquid crystal displays. Applications include display drivers for instruments (e.g., counters, DVMs, etc.), computer/calculator display drivers, steering display drivers, and various clocks, meters, and timers.
