Description

The MC14511B BCDtoseven segment latch/decoder/driver is constructed with complementary MOS (CMOS) enhancement mode devices and NPN bipolar output drivers in a single monolithic structure. The MC14511B provides the functions of a 4bit storage latch, an 8421 BCDtoseven segment decoder, and an output drive capability. Lamp test (LT), blanking (BI), and latch enable (LE) inputs are used to test the display, to turnoff or pulse modulate the brightness of the display, and to store a BCD code, respectively. MC14511B can be used with sevensegment lightemitting diodes (LED), incandescent, fluorescent, gas discharge, or liquid crystal readouts either directly or indirectly.

Applications of MC14511B include instrument (e.g., counter, DVM, etc.) display driver, computer/calculator display driver, cockpit display driver, and various clock, watch, and timer uses.
