lamp test feature for display diagnostics.

The CD4511 DIP BCD to Seven-Segment Latch/Decoder/Driver is a CMOS IC that converts BCD input (4-bit binary) to seven-segment display output for driving LEDs or LCDs. It features a lamp test input for display diagnostics, a latch input for stable data output, and operates over a wide voltage range (3V to 18V). The IC is ideal for use in digital clocks, numeric displays, test equipment, and automation systems, packaged in a DIP-16 format for easy integration into breadboards and PCBs.
