NSC CD4511BCN

CD4511BM/CD4511BC BCD-to-7 Segment
Latch/Decoder/Driver
General Description
Features
The CD4511BM/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-toseven 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 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.
