CD4511BC BCD-to-7 Segment Latch/Decoder/Driver
General Description
The CD4511BC 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...
