MC14511B Datasheet Bcd-to-seven Segment Latch/decoder/driver

Manufacturer: onsemi

Overview: DATA SHEET www.onsemi.com BCD-to-Seven Segment Latch/Decoder/Driver MC14511B 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.
