CMOS MSI (Low–Power Complementary MOS)
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.
