The HD74HC147

priority encoding of the inputs to ensure that only the highest order data line is encoded. Nine input lines are encoded to a four line BCD output. The implied decimal zero codition requires no input condition as zero is encoded when all nine data lines are at a high logic level. All data inputs and outputs are active at the low logic level. Features.
High Speed Operation: tpd = 14.5 ns typ (CL = 50 pF) High Output Current: Fanout of 10 LSTTL Loa.
