Description

The 74LS47 is a TTL logic BCD to 7-segment decoder/driver IC designed to drive 7-segment displays. It converts a 4-bit binary-coded decimal (BCD) input into a 7-segment output, which can directly drive a 7-segment LED display. The IC includes output drivers capable of sourcing or sinking current for the segments, making it suitable for use in digital displays.

Features

  • BCD to 7-segment decoding: Converts a 4-bit BCD input into the appropriate 7-segment display code.
  • 7-segment display driving: Drives 7-segment displays directly, with current-limiting resistors typically required.
  • Active-low outputs: Outputs are active low, meaning that the segments light up when the output is low.
  • Lamp test and blanking: Includes lamp test (LT) and blanking (BL) inputs for display testing and turning off the display, respectively.
  • Decimal point control: Decimal point (DP) output to control an additional segment if needed.
  • Wide operating voltage range: Operates from 4.75V to 5.25V (TTL logic).

Specifications

  • Package Type: DIP-16 (Dual In-line Package)
  • Number of Inputs: 4 (BCD input)
  • Number of Outputs: 7 (to 7-segment display)
  • Supply Voltage (Vcc): 4.75V to 5.25V
  • Maximum Input Frequency: Not applicable (static decoding)
  • Propagation Delay Time: 25 ns (typical at 5V)
  • Output Drive Current: ±25 mA (source/sink)
  • Operating Temperature: 0°C to 70°C
