MC14511B BCD-To-Seven Segment Latch/Decoder/Driver
The MC14511B 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 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 disc...
