Except for "Operating Temperature Range" they are not meant to imply that thedevices should be operated at these limits. The table of "Electrical Characteristics" provides conditionsfor actual device operation.Note 2: Unless otherwise specified min/max limits apply across the _55°C to +125°C temperaturerange for the DM5488 and across the O°C to 70°C range for the DM7488.

«0000~.....~c.......«0000~Ln~Ctruth tablesDM5488A/DM7488A SINE LOOK-UP TABLEA pattern has been generated for the DM5488/DM7488. The AA pattern provides a sine table. The 5-bit inputcode linearly divides 90° into 32 equal segments. Each 8-bit output is therefore the sine of the angle applied.EXAMPLE: Input 11010 means 26/32 of 90 0 , or about 73 0 • The corresponding output 11110100 indicates(1/2 + 1/4 + 1/8 + 1/16 + 1/64) or about .95, which is close to the sine of 73 0 • Rounding-off has not beenemployed, since without rounding-off it is possible to extend the accuracy with additional ROMs.INPUTSOUTPUTSWORD BINARY SELECT ENABLEE 0 C A•G V8 V7 V6 V5 y, V3 V2 V,0 0 0 0 0 0 0 0 0 0 00 0 0 0, 0 0 0 0,0 0 0 0 0 , , 0 02 0 0 0 , 0 0 0 0 0 1, 0 0 ,3 0 0 0 1,0 0 0 , 0 0 1 0 ,, 0 0, 0 0 0 0 0 , , 0 0 0 15 0 0 , 0,0 0 0 , , , , 1 09 0 1 0 0 1 0 0 1 1 0 1 1 0 110 0 1 0 0 0 0 , 1 1, 0 0 00 1 0 ,"1 0, 0 0 0 0 0 1 ,12 0 1 1 0 0 0 1 0 0 0 , , ,013 0 1 0 1 0 0 0 , 1 0 0 014 0 , 1 0 0 0 0 0 0 1 0'5 0 , 1 1,0, 0,0 1 0 1,,.161711100000000,0100001,100,11011001011,000,1119 1 0 0 , 1 0 1 , 0 0, , 0 ,20 , 0 , 0 0 0 1 , 0 , 0 1 0 021 1 0 1 0 1 0,1 0 , , 0,122 1 0 1, 0 0,1 1 0 0 0 0 123 1 0 , , , 0 ·1 , , 0 0 1 1 124 , 1 0 0 0 0,1 1 0 1 1 0 025 1, 0 0 1 0 1 , , , 0 0 0 126 , 1 0 1 0 0,1 1, 0 1 0 027 , 1 0 , 1 0 1, 1 1 , 0 0 02. 1 , , 0 0 0 1 , , , , 0,130 1 1-00 1, 1 1 1 1 00 1 1 1 1 0 129 1,1, 0,, , ,31 1 , 1 1 1 0, ,1 1,1, ,1,All X X X X X 1 1 1x - Don't CareDM5488/DM7488 TRUTH TABLEThe output levels are not shown on the truth table since the customer specifies the output condition he desiresat each of the eight outputs for each of the 32 words (256 bits).
