SN74LS247N (74LS247) Logic chip

Description:

The SN74LS247N integrates internal logic to decode four lines of BCD (Binary-Coded Decimal) data into the 7-segment format. It is capable of directly driving a common-cathode LED display or other types of 7-segment displays through its outputs, which correspond to each segment of the display.

Key Features:

• BCD to 7-segment decoder/driver
• Direct drive for common-cathode LED displays
• Internal pull-up resistors on inputs
• Operating voltage: 4.75V to 5.25V
• Low power consumption
• High-speed TTL (Transistor-Transistor Logic) technology
• Active-low blanking input for display blanking control

Technical Specifications:

• Package Type: 16-pin DIP (Dual In-line Package)
• Supply Voltage (V_CC): 4.75V to 5.25V
• Input Voltage (V_IN): 0V to V_CC
• Output Voltage (V_OUT): 0V to V_CC
• Input High Voltage (V_IH): 2V (minimum)
• Input Low Voltage (V_IL): 0.8V (maximum)
• Output Current (I_O): 16mA (maximum per segment)
• Quiescent Supply Current (I_CC): 6mA (maximum)
• Propagation Delay Time: 30ns (typical)
• Operating Temperature Range: 0°C to +70°C

Applications:

• Digital Panel Meters
• Scoreboards
• Counters
• Timers
• Clocks
• Industrial Control Systems
