February 1988
CD4511BM CD4511BC BCD-to-7Segment 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 8421BCD-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
