SEMICONDUCTOR TECHNICAL DATA

2-Bit by 2-Bit Parallel

Binary Multiplier

complementary MOS (CMOS) enhancement mode devices. The multiplier

can perform the multiplication of two binary numbers and simultaneously add

two other binary numbers to the product. The MC14554B has two

multiplicand inputs (X0 and X1), two multiplier inputs (Y0 and Y1), five

cascading or adding inputs (K0, K1, M0, M1, and M2), and five sum and

carry outputs (S0, S1, S2, C1 [S3], and C0). The basic multiplier can be

expanded into a straightforward m–bit by n–bit parallel multiplier without

additional logic elements.

dividing), Fast Fourier Transform processing, digital filtering, communica-

tions (convolution and correlation), and process and machine controls.

voltages or electric fields. However, pre-

cautions must be taken to avoid applications of

any voltage higher than maximum rated volt-

ages to this high–impedance circuit. For proper

operation, V in and V out should be constrained

to the range V SS
