UTCMC14511 CMOS IC BCD-TO-SEVEN SEGMENT LATCH/DECODER/DRIVER

The UTC MC14511 BCD–to–seven segment latch/decoder/driver is constructed with complementary 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 l.
