MC14580B 4 x 4 Multiport Register
The MC14580B is a 4 by 4 multiport register useful in small scratch pad memories, arithmetic operations when coupled with an adder, and other data storage applications. It allows independent reading of any two words (or the same word at both outputs) while writing into any one of four words. Address changing and data entry occur on the rising edge of the clock. When the write enable input is low, the contents of any word may be accessed but not altered. * * * * * No Restrictions on Clock Input Rise or Fall Times 3-State Outputs Single Phase Clocking Supply Voltage Range = 3.0 Vdc to 18 Vdc Capable of Driving Two Low-power TTL Loads or one Low-power Schottky TTL Load Over the Rated Temperature Range * Pin Compatible with CD40108 MAXIMUM RATINGS* (Voltages Referenced to VSS)

To calculate total supply current at loads other than 50 pF: IT(CL) = IT(50 pF) + (CL - 50) Vfk where: IT is in A (per package), CL in pF, V = (VDD - VSS) in volts, f in kHz is input frequency, and k = 0.004. 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 high-impedance 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.
