MC14511B/D
MC14511B
BCD-to-Seven Segment
Latch/Decoder/Driver
The MC14511B 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−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.
