MC14511B BCD−To−Seven Segment Latch/Decoder/Driver
€1.00
Tax included
CMOS BCD-to-7-segment latch/decoder/driver with high-current outputs (up to 25 mA). Operates from 3.0 V to 18 V with integrated lamp test, blanking, and latch enable functions.
The MC14511B is a CMOS integrated circuit combining a 4-bit storage latch, an 8421 BCD-to-seven-segment decoder, and an output driver. Constructed with complementary MOS enhancement devices and NPN bipolar output drivers, it provides high-current sourcing capability (up to 25 mA) to directly drive seven-segment LEDs, incandescent lamps, gas discharge, or liquid crystal displays.
The device features Lamp Test (LT), Blanking (BI), and Latch Enable (LE) inputs for display control, brightness modulation, and code storage. Operating over a supply voltage range of 3.0 V to 18 V, it automatically blanks illegal input combinations. Typical applications include instrument displays, counters, clocks, calculators, and cockpit readouts.
