CD4511BM CD4511BC BCD-to-7 Segment
Latch Decoder Driver
General Description
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
Applications include instrument (e g
counter DVM etc )
display driver computer calculator display driver cockpit
display driver and various clock watch and timer uses
