FAST AND LS TTL DATA
8-INPUT SHIFT/STORAGE
REGISTER WITH SYNCHRONOUS
RESET AND COMMON I/O PINS
The MC74F323 is an 8-Bit Universal Shift/Storage Register with 3-state
outputs. Its function is similar to the F299 with the exception of Synchronous
Reset.
The parallel load inputs and flip-flop outputs are multiplexed to reduce the
total number of package pins. Separate outputs are provided for flip-flops Q
0
and Q7 to allow easy cascading. A separate active LOW Master Reset is used
to reset the register.
Four modes of operation are possible: hold (store), shift left, shift right and
parallel load. All modes are activated on the LOW-to-HIGH transition of the
clock.
• Common I/O For Reduced Pin Count
• Four Operation Modes: Shift Left, Shift Right, Parallel Load and Store
• Separate Continuous Inputs and Outputs from Q
0
and Q7 Allow Easy
Cascading
• Fully Synchronous Reset
• 3-State Outputs for Bus Oriented Applications
• Input Clamp Diodes Limit High-Speed Termination Effects
