4511 BCD to 7-Segment Decoder/Driver IC

The 4511 is a CMOS integrated circuit that decodes 4-bit BCD inputs and drives a 7-segment display.
It converts binary-coded decimal values into corresponding segment control signals.
The device provides latched, active-high outputs suitable for common-cathode 7-segment displays.
It operates from a wide single-supply voltage range and supports display blanking control.
Typical applications include numeric displays in counters, clocks, measurement equipment, and control panels.
