Functional Description

The CD4028BNSR decoder features a set of four input pins that accept binary coded decimal values. These inputs are decoded to drive one of the ten output lines low, providing a decimal decoded output. The outputs are designed to interface with common types of digital circuitry and are capable of driving up to 10 LS-TTL loads. The high sink current capability of the outputs ensures reliable operation in the presence of variations in supply voltage and temperature.

Applications

Due to its decoding capabilities, the CD4028BNSR is suitable for a wide range of applications, including:

• Decimal point decoding in digital displays
• Address decoding for memory and port mapping
• Control logic for multiplexing and demultiplexing
• Input/output interfaces for microprocessors
• Electronic voting machines
• Instrumentation and measurement systems
