Overview
The CD40147BEG4, produced by Texas Instruments, is a CMOS BCD priority encoder. This integrated circuit is designed to encode ten data input lines (0-9) into a four-line BCD (8, 4, 2, 1) output. The encoder prioritizes the inputs, ensuring that only the highest-order data line is encoded, with line 9 being the highest priority. The device is functionally similar to the TTL 54/74147 if pin 15 is tied low.
The CD40147BEG4 is available in various package types, including 16-lead dual-in-line plastic packages (PDIP), 16-lead small-outline packages (SOIC), and 16-lead thin shrink small-outline packages (TSSOP), making it versatile for different design requirements.
