Working Principles

The CD4028BNSR is a BCD-to-decimal decoder that converts a 4-bit binary-coded decimal input to a 7-segment display output. The inputs A0, A1, A2, and A3 represent the BCD input bits, while the outputs A to F drive the corresponding segments of a 7-segment display. The LT input allows testing of the display, and the BI/RBO input controls blanking or ripple-blanking functions. The CCO output provides a carry-out signal for cascading multiple decoders.

Detailed Application Field Plans

The CD4028BNSR can be used in various applications, including: - Digital clocks and timers - Counters and frequency dividers - Industrial control systems - Instrumentation panels - Consumer electronics devices
