UNISONIC TECHNOLOGIES CO., LTD MC14511 BCD-TO-SEVEN SEGMENT LATCH/DECODER/DRIVER - DESCRIPTION The UTC MC14511 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,...
