Introduction

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(overline)), blanking (BI(overline)), 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.
