Details

Texas Instruments' CD4511BCN is a reliable BCD-to-7 segment latch/decoder/driver IC designed to seamlessly convert BCD data input into 7-segment display outputs. Its ability to drive both common-cathode or common-anode displays makes it a versatile choice for a wide range of display applications. The IC's latch enable input, BCD inputs, and active-low lamp test and blanking inputs provide precise control over the display output, while its seven buffered outputs ensure efficient driving of the segments of a 7-segment display. Operating within a supply voltage range of 3V to 18V, and featuring a maximum input current of 1µA and output current of 5.5mA, the CD4511BCN is a reliable and efficient choice for applications such as digital clocks, counter displays, and instrumentation panels

Key Features

  • Low logic circuit power dissipation
  • High current sourcing outputs (up to 25 mA)
  • Latch storage of code
  • Blanking input
  • Lamp test provision
  • Readout blanking on all illegal input combinations
  • Lamp intensity modulation capability
  • Time share (multiplexing) facility
  • Equivalent to Motorola MC14511

FAQs

What is CD4511BCN?

The CD4511BCN is a BCD to 7-segment latch/decoder/driver designed by Texas Instruments. It is commonly used to drive 7-segment displays in digital display applications, such as digital clocks, electronic meters, and panel meters.

How Does CD4511BCN Work?

The CD4511BCN works by taking a 4-bit BCD (Binary-Coded Decimal) input and converting it into the necessary signals to drive a 7-segment display. It includes a latch to store the BCD input and a decoder to convert the BCD code to the appropriate signals for the 7-segment display. The device also features integrated current-limiting resistors for simplified interfacing with the display.

How Many Pins does CD4511BCN have and What are the Functions of the Pinout Configuration?

The CD4511BCN is housed in a 16-pin PDIP (Plastic Dual In-Line Package) package. The pinout configuration includes:

  • LT/BI: Latch Enable/Input Buffer Enable pin.
  • BI/RBO: Blanking Input/ripple-blanking output pin.
  • A, B, C, D: BCD input pins.
  • a, b, c, d, e, f, g: Output pins for the segments of the 7-segment display.
  • RBO: Ripple-blanking output pin.
  • VSS: Ground pin.
  • LT/VDD: Latch Enable/Input Buffer Enable pin and positive power supply pin.

What are the Pros and Cons of CD4511BCN?

Pros:

  • Easy Interface: Simplifies the driving of 7-segment displays with integrated current-limiting resistors.
  • BCD Input: Directly accepts BCD input, making it easy to use with binary counters and digital systems.
  • Latch Function: Includes a latch for storing the BCD input, allowing synchronous display updates.
  • Low Power Consumption: Operates with low power, suitable for battery-powered devices.
  • Cost-Effective: Provides cost-effective driving of 7-segment displays without the need for additional components.

Cons:

  • Limited to 7-Segment Displays: Designed specifically for driving 7-segment displays and may not be suitable for other display types.
  • Not Suitable for Graphic Displays: Limited to displaying numerical digits and simple characters on 7-segment displays.
  • Limited Functions: May not provide advanced display control features available in more sophisticated display driver ICs.

Are There Any Equivalents/Alternatives to CD4511BCN for Recommendation?

  • Alternatives to the CD4511BCN include the 74LS47 BCD to 7-segment decoder/driver and the CD4510 BCD up/down counter, which can be used in conjunction with a separate 7-segment driver.
