Overview
The MC14511BDG, produced by onsemi, is a BCD-to-seven segment latch/decoder/driver integrated circuit. It is constructed with complementary MOS (CMOS) enhancement mode devices and NPN bipolar output drivers in a single monolithic structure. This device provides the functions of a 4-bit storage latch, an 8421 BCD-to-seven segment decoder, and an output drive capability. It is designed to work with various display types such as seven-segment light-emitting diodes (LED), incandescent, fluorescent, gas discharge, or liquid crystal readouts.
