MC14511B Datasheet, PDF (1/12 Pages) ON Semiconductor – BCD-To-Seven Segment Latch/Decoder/Driver

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.
