The SN74LS173N is a high-speed 4-BitRegister featuring 3-state outputs foruse in bus-organized systems. The clock is fully edge-triggered allowingeither a load from the D inputs ora hold (retain register contents) dependingon the state of the Input Enable Lines (IE1, IE2).
A High on either Output Enable line (OE1, OE2) brings the output to a high impedance state without affecting the actual register contents. A High on the Master Reset (MR)input resets the Register regardless of the state of theClock (CP), the Output Enable (OE1, OE2) or the Input Enable (IE1, IE2) lines.
