Processor

Package Types:	Package Types:
Function:	Converts 4-bit BCD input to 7-segment display output.
Inputs	BCD Inputs: 4-bit binary inputs (A, B, C, D) to represent decimal digits (0-9). Enable Inputs: LE (Latch Enable): Latches the BCD input data into the internal register when enabled. BI (Blanking Input): Blanks the display if active (low level). LT (Lamp Test): Turns on all segments for testing if active (low level).
Outputs	Seven Segments (a-g): Open-collector outputs connected to the segments of the 7-segment display. Blanking and Lamp Test: Control and test the display.
Operating Voltage:	Typically operates between 4.75V to 5.25V.
Current	Output Drive Current: Can source/sink typically up to 25 mA per segment. Input Current: Low input current for digital inputs.
Open Collector:	Requires external pull-up resistors.
Temperature Range:	Typically operates within 0°C to 70°C or -40°C to 85°C for industrial-grade versions.
