MC14513 DIP IC

The MC14513B 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 has 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. The Ripple Blanking Input (RBI) and
Ripple Blanking Output (RBO) can be used to suppress either leading
or trailing zeroes. 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.
