74HC164

The 74HC164 is an 8-bit serial-in parallel-out shift register. It is used to expand the number of outputs available from a microcontroller or other digital system. Data is serially entered into the shift register and can be accessed in parallel, making it useful for driving multiple LEDs, displays, or other digital outputs.

Key Features:

• 8-bit serial-in parallel-out shift register
• High-speed CMOS technology
• Wide operating voltage range
• Low power consumption
• Suitable for driving LEDs and displays
• High noise immunity

Technical Specifications:

• Number of Bits: 8
• Operating Voltage: 2V to 6V
• Logic Levels: TTL-compatible
• Propagation Delay: 9ns (typical) at 5V
• Current Output: 25mA (max) per output
• Package Type: DIP-16, SOIC-16, TSSOP-16

Applications:

• LED displays and indicators
• Keypad interfaces
• Data bus expansion
• Shift registers in digital systems
• Digital signal processing

Usage:

1. Connect the serial data input to the data source.
2. Apply a clock pulse to the CLK input to shift data into the register.
3. Use the parallel output pins to access the stored data.
4. Connect the outputs to external devices such as LEDs or displays.

Caution:

• Do not exceed the maximum supply voltage of 6V.
• Ensure correct polarity of connections to avoid damage.
• Observe proper handling to prevent static discharge damage.
