CD4511BPWR

CD4511BPWR is a CMOS BCD-to-7-segment decoder/driver with a latch. It converts a 4-bit BCD input (A–D) into seven segment outputs (a–g) to drive a common-cathode LED display. It includes control features: LE (Latch Enable), LT (Lamp Test), BI (Blanking Input), and RBI (Ripple Blanking Input) for display blanking/test operations. Outputs can source/sink a few milliamps per segment; use current-limiting resistors. Supply voltage range is typically 3–18 V (5 V common). Package: 16-pin DIP (BPWR variant indicates a Plastic DIP wide-package). It does not provide a decimal point output—an external driver is needed for DP if required. Typical uses: digital clocks, meters, counters, numeric displays. Basic hookup: connect A–D to your BCD source; connect a–g to the display segments via resistors; set LT/BI/RBI per desired mode; optionally use LE to latch new values.

CD4511BPWR is a CMOS BCD-to-7-segment latch/decoder/driver. Key features:
- 4-bit BCD inputs (A–D) and outputs for seven segments (a–g) plus DP.
- Built-in latch with LE (latch enable) to hold the displayed digit.
- Lamp Test (LT) to illuminate all segments for testing.
- Blanking Input (BI) to turn off all segments.
- Suitable for driving common-anode LED displays (outputs sink current).
- Wide supply range: typically 3 V to 18 V (CMOS safe).
- Low power consumption.
- 16-pin package (BPWR variant: DIP/SO-style option available).

CD4511BPWR is a 16-pin CMOS BCD-to-7-segment latch/decoder/driver. It decodes a 4-bit BCD input (A–D) to seven segment outputs (a–g) to drive a display, with a latch enable (LE) to capture data, a lamp test (LT) for testing all segments, and a blanking input (BI) to blank the display. It does not provide a decimal-point output. Power pins are VDD and VSS (as with a standard DIP-16 package).

- Manufacturer: Texas Instruments (TI).
- Company type: American multinational semiconductor company that designs and manufactures analog, digital, mixed-signal, and embedded processing integrated circuits.

CD4511BPWR is a CMOS BCD-to-7-segment latch/decoder/driver with A–D inputs, outputs a–g and DP, plus LE, LT and BI. It drives common-anode 7-segment displays by sinking current and supports multiplexed displays. Applications include digital clocks and timers, calculators, digital readouts (panel meters, voltmeters, multimeters), counters and scoreboards, and other instrumentation or consumer appliances needing a 7-seg readout. Operates from 3–18 V.
