8 Input Universal Shift/Storage Register with Common Parallel I/0 Pins
The MC74AC299/74ACT299 is an 8-bit universal shift/storage register with 3-state outputs. Four modes of operation are possible: hold (store), shift left, shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Additional outputs are provided for flip-flops Q0, Q7 to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register. * * * * * * Common Parallel I/O for Reduced Pin Count Additional Serial Inputs and Outputs for Expansion Four Operating Modes: Shift Left, Shift Right, Load and Store 3-State Outputs for Bus-Oriented Applications Outputs Source/Sink 24 mA ACT299 Has TTL Compatible Inputs

FUNCTIONAL DESCRIPTION
The MC74AC299/74ACT299 contains eight edge-triggered D-type flip-flops and the interstage logic necessary to perform synchronous shift left, shift right, parallel load and hold operations. The type of operation is determined by S0 and S1, as shown in the Truth Table. All flip-flop outputs are brought out through 3-state buffers to separate I/O pins that also serve as data inputs in the parallel load mode. Q0 and Q7 are also brought out on other pins for expansion in serial shifting of longer words. A LOW signal on MR overrides the Select and CP inputs and resets the flip-flops. All other state changes are initiated by the rising edge of the clock. Inputs can change when the clock is in either state provided only that the recommended setup and hold times, relative to the rising edge of CP, are observed. A HIGH signal on either OE1 or OE2 disables the 3-state buffers and puts the I/O pins in the high impedance state. In this condition the shift, hold, load and reset operations can still occur. The 3-state buffers are also disabled by HIGH signals on both S0 and S1 in preparation for a parallel load operation. TRUTH TABLE
