74HC147 Description
The ’HC147 and CD74HCT147 are high speed silicon-gate CMOS devices and are pin-patible with low power Schottky TTL (LSTTL). The ’HC147 and CD74HCT147 9-input priority encoders accept data from nine active LOW inputs (l1 to l9) and provide binary representation on the four active LOW inputs (Y0 to Y3). A priority is assigned to each input so that when two or more inputs are simultaneously active, the input with the...
