Step of 8 9.02DP Consider the expression for the ROM size. ROM size = 2" xm Where, n is the number of input lines m is the number of output lines Step of 8 74x49 is a BCD to 7-segment Decoder which has 4 BCD inputs B₀, B1, B2, B, and 7 outputs a,b,c,d,e,f,g The number of inputs n is 4 The number of inputs m is 7 Calculate the ROM size. ROM size = 2" = 16x7 Therefore, the ROM size for 74x49 is Step of 8 74x139 is a Dual 1-of-4 Decoder which has 3 inputs E, A₀, and 4 outputs B₀, B1, B2, The number of inputs n is 3 The number of inputs m is 4 Calculate the ROM size. ROM size = 2" =8x4 Therefore, the ROM size for 74x139 is 8x4 Step of 8 74x153 is a Dual 4 1 Line Data selector Multiplexer which has 10 inputs IG, IC₀, IC2, 2G, 2C1, 2C2, 2C, and 2 outputs Y2 The number of inputs n is 10 The number of inputs m is 2 Calculate the ROM size. ROM size 2" =1024x2 Therefore, the ROM size for 74x153 is 1024x2 Step of 8 74x257 is a 2 input-4 bit Multiplexer which has 9 inputs and 4 outputs The number of inputs n is 9 The number of inputs m is 4 Calculate the ROM size. ROM size 2" xm =512x4 Therefore, the ROM size for 74x257 is 512x4 Step of 8 74x381 is a 4-bit Arithmetic logic unit (ALU) which has 12 inputs C, and 6 outputs G, The number of inputs n is 12 The number of inputs m is 6 Calculate the ROM size. ROM size = 2" = 4096x6 Therefore, the ROM size for 74x381 is 4096x6 Step of 8 74x682 is an 8-bit comparator which has 16 inputs and 2 outputs (A=B), (A>B) The number of inputs n is 8 The number of inputs m Calculate the ROM size. ROM size = 2" xm 65536x2 Therefore, the ROM size for 74x682 is 65536x2 Step of 8 Consider the following tabular form: Table 1 MSI parts Description ROM Size 74x49 BCD to 7-segment Decoder 16x7 74x139 Dual 1-of-4 Decoder 8x8 74x153 Dual 4 Line-1 Line Data selector Multiplexer 1024x2 74x257 bit multiplexer 512x4 74x381 4-bit Arithmetic logic unit(ALU) 4096x6 74x682 8 bit Comparator 65536x2
