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.

When either OE1, or OE2 are HIGH, the output is in the off state (High Impedance);
however this does not affect the contents or sequential operation of the register.
