Key Features
- Gated Serial Inputs: The gated serial inputs (A and B) allow complete control over incoming data, inhibiting entry of new data and resetting the first flip-flop to the low level at the next clock pulse if either input is low.
- Fully Buffered Clock and Serial Inputs: Ensures stable and reliable operation of the clock and serial inputs.
- Asynchronous Clear: Allows for immediate clearing of the register without waiting for a clock pulse.
- Diode-Clamped Inputs: Minimizes transmission-line effects.
Applications
The SN74LS164NSRE4 is suitable for a variety of digital circuit applications, including:
- Serial-to-Parallel Data Conversion: Converting serial data streams into parallel data for processing.
- Shift Register Applications: Used in circuits where data needs to be shifted serially.
- Digital Signal Processing: In systems requiring precise control over data flow and timing.
