74HC147 – 74147 ( 10-to-4 Line Priority Encoder )

74HC147-74147 (10-to-4 Line Priority Encoder) is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. CD74HC147E provide the 10-line to 4-line priority encoding function by use of the implied decimal “zero”. The “zero” is encoded when all nine data inputs are HIGH, forcing all four outputs HIGH. FEATURES Encodes 10-line decimal to 4-line BCD Useful for 10-position switch encoding Used in code converters and generators Output capability: standard ICC category: MS Specification Propagation Delay Time: 160 ns at 2V / 27 ns at 6V at 25°C Output Current: 5.2 mA at 6 V No. of Pins: 16 Operating Temperature Range : -40°C to +125°C Supply Voltage Range: 2V to 6V Package: DIP-16 Symbol PIN Description Y0 to Y3 9,7,6,14 enable input (active LOW) A0 to A8 11,12,13,1,2,3,4,5,10 address input n.c. 15 output (active LOW) GND 8 ground (0 V) VCC 16 positive supply voltage It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
