概要

Description

CD4511BPWR is a CMOS BCD-to-7-segment latch/decoder/driver (CD4511) in a 16‑pin package.
Key points:
- Converts 4-bit BCD inputs (0–9) to seven-segment outputs (a–g) to drive a display.
- Features: latch enable (LE) to hold a digit for multiplexing, lamp test (LT) to light all segments, and blanking input (BI) to blank the display.
- Designed to drive common-cathode 7-segment displays; requires current-limiting resistors on each segment.
- Supply range: typical 3–15V (often used at 5V logic levels); inputs are CMOS-compatible.
- Package: BPWR denotes a specific 16‑pin plastic package variant.
Typical use: digit drivers in digital clocks, meters, or any multi-digit display requiring a BCD input with clean, flicker-free multiplexing.

Features

CD4511BPWR is a CMOS BCD-to-7-segment latch/decoder/driver. Key features:
- 4-bit BCD input (A–D) → 7-segment outputs (a–g) for LED displays
- Latch Enable (LE) allows digits to be held while inputs change
- Lamp Test (LT) to illuminate all segments for testing
- Blanking inputs: BI (blanking) and RBI (ripple blanking) for zero suppression/blanking
- Outputs are active-low and sink current (suitable for common-anode displays)
- Wide supply range: typically 3 V to 18 V CMOS operation
- Low power consumption and TTL/CMOS compatible
- 14-pin package (CD4511BPWR variant in plastic DIP/SOIC formats)
- Part of 4000-series CMOS—simple interfacing, no external timing components required
Note: Always check exact package and polarity in the specific datasheet variant.

Package

CD4511BPWR is a 16-pin Plastic Dual Inline Package (PDIP, DIP-16).

Pinout

- Pin count: 16 pins (DIP-16, also available in other 16-pin packages).
- Function: CMOS 4-bit BCD-to-7-segment latch/decoder/driver. Decodes BCD inputs (A–D) to seven segment outputs (a–g) with an internal latch; outputs are active-low to drive common-anode LEDs. Also provides lamp test, blanking, and ripple-blanking features for multi-digit displays.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational technology company that designs and manufactures semiconductors and integrated circuits (analog, digital, embedded processors, etc.), and is one of the world’s largest semiconductor producers.

Application

CD4511BPWR is a CMOS BCD-to-7-segment latch/decoder/driver with LE, LT, and BI inputs. It converts 4-bit BCD to seven-segment outputs (plus DP) to drive LED displays. Applications: digital clocks, meters/panel indicators, counters, calculators, and measurement instruments; microcontroller display interfaces; suitable for multiplexed displays with digit scanning; supports common-anode or common-cathode displays with proper wiring.
