ON DELAYS tPLH = tPHL DE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V to 6 V N AND FUNCTION COMPATIBLE WITH 54/74LS147 B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) ORDER CODES : M54HC147F1R M74HC147M1R M74HC147B1R M74HC147C1R The M54/74HC147 is a high speed CMOS 10 TO 4 LINE PRIORITY ENCODER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. This device features 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 condition requires no input condition as zero is encoded when all nine data lines are at high logic level. All data input and outputs are active at the low logic level. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
