CMOS BCD to 7-Segment Latch Decoder Driver

High-Reliability BCD to 7-Segment Decoder Driver IC

The NTE4511B is a CMOS BCD to 7-segment latch decoder driver engineered for precision and reliability in digital display applications. Designed to interface directly with common-cathode 7-segment LED displays, this integrated circuit combines robust output sourcing capability with versatile input control for consistent, dependable results in demanding designs.

Key Features & Technical Specifications

• Latch, Decoder, and Driver Functionality – Combines BCD code input latching, decoding, and direct 7-segment LED driving in a single CMOS device.
• Wide Supply Voltage Range: Operates from 3V to 15V, accommodating various logic families and power supply constraints.
• High Output Drive: Capable of sourcing up to 25mA per segment, enabling direct interface with LED display segments without the need for additional drivers.
• Low Quiescent Power Consumption: CMOS technology ensures minimal static supply current in standby conditions, supporting energy-efficient system design.
• Input Controls:
  • Latch Enable (LE): Latches the BCD input state for stable display output.
  • Lamp Test (LT): Illuminates all segments for system and display diagnostics.
  • Blanking (BL): Allows display blanking control for multiplexing or intensity adjustment.
• Operating Temperature Range: -55°C to +125°C
• Package: 16-lead Dual-In-Line Package (DIP)
• Quantity: 1 IC per package
• Part Number: NTE4511B

Applications

• Digital clocks and timers
• Instrumentation and process control displays
• Numeric data visualization in industrial and commercial electronics
• LED display multiplexing

Usage Instructions

Apply BCD (Binary-Coded Decimal) inputs to the A, B, C, and D pins. Use the Latch Enable to freeze input data for steady display output. Lamp Test can be activated to illuminate all display segments simultaneously for diagnostics. The Blanking input allows for easy control over segment illumination, supporting advanced display management or power-saving modes.
