4-BIT D-TYPE REGISTER WITH 3-STATE OUTPUTS The SN54 / 74LS173A is a high-speed 4-Bit Register featuring 3-state outputs for use in bus-organized systems. The clock is fully edge-triggered allowing either a load from the D inputs or a hold (retain register contents) depending on 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 the Clock (CP), the Output Enable (OE1, OE2) or the Input Enable (IE1, IE2) lines.
