CD4511BM/CD4511BC BCD-to-7 Segment  
Latch/Decoder/Driver  
General Description  
Features  
Y
Low logic circuit power dissipation  
The CD4511BM/CD4511BC BCD-to-seven segment latch/  
decoder/driver is constructed with complementary MOS  
(CMOS) enhancement mode devices and NPN bipolar out-  
put drivers in a single monolithic structure. The circuit pro-  
vides 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 emit-  
ting diodes (LED), incandescent, fluorescent, gas discharge,  
or liquid crystal readouts either directly or indirectly.  
Y
High current sourcing outputs (up to 25 mA)  
Latch storage of code

Lamp test provision  
Readout blanking on all illegal input combinations  
Lamp intensity modulation capability  
Time share (multiplexing) facility  
Equivalent to Motorola MC14511  
Applications include instrument (e.g., counter, DVM, etc.)  
display driver, computer/calculator display driver, cockpit  
display driver, and various clock, watch, and timer uses.
