40147------4-line priority encoder (BCD output)Brief description: The 40147 encoder has the function of priority encoding of input signals, which can ensure that only the highest-level data lines are encoded. 10 data input lines (0-9) are encoded into four lines (A-D) (BCD output). The highest priority line is the ninth line. When all input lines are logic 0, all output lines are logic 1. All inputs and outputs are buffered, and each output can drive a TTL low-power Schottky load.
