数据手册.pdfON SEMICONDUCTOR MC14511BCPG 芯片, 4000系列 CMOS逻辑器件
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, 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. 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.
