MC14554B 2-Bit by 2-Bit Parallel Binary Multiplier
The MC14554B 2 x 2bit parallel binary multiplier is constructed with 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 mbit by nbit parallel multiplier without additional logic elements. Application areas include arithmetic processing (multiplying/adding, obtaining square roots, polynomial evaluation, obtaining reciprocals, and dividing), Fast Fourier Transform processing, digital filtering, communications (convolution and correlation), and process and machine controls. · · · · · · · · Diode Protection on All Inputs All Outputs Buffered Straightforward mBit By nBit Expansion No Additional Logic Elements Needed for Expansion Multiplies and Adds Simultaneously Positive Logic Design Supply Voltage Range = 3.0 Vdc to 18 Vdc Capable of Driving Two LowPower TTL Loads or One LowPower Schottky TTL Load Over the Rated Temperature Range

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this highimpedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS (Vin or Vout) VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.
