SN74LS164(74LS164)

The SN74LS164 is an 8-bit serial-in parallel-out shift register from the 74LS series of TTL logic ICs. It features two serial data inputs (A and B), which can be used for either single or dual data input configurations. The parallel outputs provide the ability to shift in serial data and obtain parallel data output, making it ideal for data conversion, storage, and transfer applications in digital circuits.

Key Features:

• 8-bit serial-in parallel-out shift register
• Two serial data inputs for flexible data entry
• High-speed operation
• Direct clear input for resetting the register
• Low power consumption
• Standard 14-pin DIP package
• TTL-compatible inputs and outputs

Technical Specifications:

• Supply Voltage (VCC): 4.75V to 5.25V
• High-Level Input Voltage (VIH): 2V (min)
• Low-Level Input Voltage (VIL): 0.8V (max)
• High-Level Output Voltage (VOH): 2.7V (min) at IOH = -0.4 mA
• Low-Level Output Voltage (VOL): 0.4V (max) at IOL = 8 mA
• Input Current (II): 20 µA (max)
• Clock Frequency (fCLK): 25 MHz (typical)
• Propagation Delay Time (tpd): 22 ns (typical)
• Operating Temperature Range: 0°C to +70°C
• Package: 14-pin DIP

Applications:

• Data Conversion: Converts serial data to parallel data for processing.
• Data Storage: Temporarily stores serial data and outputs it in parallel form.
• Digital Systems: Used in digital systems for data transfer and manipulation.
• LED Display Control: Controls LED displays by converting serial data to parallel control signals.
• Microprocessor Interfaces: Interfaces with microprocessors to handle serial-to-parallel data conversion.
