The highest priority line is line 9. The 74147 74147 lacks a disable input, so the priority display logic would need external logic to prevent being overridden by another input to a different 74147. MM54HC148 MM74HCLine Priority Encoder February 1988 MM54HC148 MM74HCLine Priority Encoder General Description This priority datasheets encoder utilizes advanced silicon- gate CMOS technology It has the high noise immunity low power consumption typical of CMOS circuits as well as the speeds output drive similar to LB- TTL This priority. All four output lines are logic 1 ( VSS) when all input lines are logic 0. The 74HC/ HCT147 9- input priority encoders accept data from nine active LOW inputs to A8) and provide a binary representation on the four active LOW outputs Y3). Multiple 74148s can be cascaded by connecting EO of the high priority 74147 chip to EI of the low priority chip ( see datasheet). A 74147 can do datasheets that for any of its 10 inputs, but lacks the means of cascading out to more priority encoders. Part of the purpose of priority encoding is to display the first input to go low. Priority encoder 74147 datasheets.
The ’ datasheets 147 and ’ LS147 devices encode nine datasheets 74147 data lines to four- lineBCD. 74LS147 74LS147 10 to 4 Priority Encoder Datasheet, 74LS147 Datasheet buy 74LS147. A priority is assigned to each input so that when two more inputs are simultaneously active, the input with the highest priority is represented on the output . Ten data input linesare encoded to four- line ( 8 4, 2 1) datasheets BCD. This device features priority encoding of the inputs to ensure thatonly the highest order data lineis en- coded. TTL encoder IC 74147 IC 74148 ten- line to BCD octal to BCD priority encoder These TTL encoders feature priority datasheets decoding of the inputs to ensure that only the highest- order data datasheets line is encoded. The CD40147B CMOS encoder features priority encoding of the inputs to ensure that only the highest- order data line is encoded.
74147 Encoder is a priority encoder IC. 74LS147 provides priority decoding of the inputs to ensure that only the highest order data line is encoded. Both devices have data inputs and outputs which are active at the low logic level. The LS147 encodes nine data lines to four- lineBCD.
