Introduction
SN74HC164DR 8-Bit Serial-In Parallel-Out Shift Register
The SN74HC164DR is a high-speed 8-bit serial-in/parallel-out (SIPO) shift register manufactured by Texas Instruments (TI), designed for efficient data expansion and I/O port extension in compact, power-constrained electronic systems. Ideal for LED driving, industrial data conversion, and control signal expansion.
Core Functional Characteristics
- Serial-to-Parallel Data Conversion: Accepts serial input via two synchronized input pins (A/B) and converts to 8-bit parallel output (Q0-Q7) after 8 clock cycles.
- Cascade Expansion Capability: Serial output pin (Q7) allows cascading multiple devices for extended parallel output widths.
- Asynchronous Clear Function: Active-low clear pin (CLR) resets all register bits to 0 independently of clock signal.
- High-Speed Operation: Supports clock frequencies up to 25 MHz (at 5V) for time-sensitive applications.
