The DM74LS164N is a high-performance, 8-bit serial-in parallel-out shift register designed by ON Semiconductor. This integrated circuit is part of the 74LS logic family, known for its low power consumption and high-speed operation. The DM74LS164N is particularly suited for applications that require the conversion of serial data to parallel output formats in digital systems.
Key Features
- Logic Family: LS (Low Power Schottky)
- Operating Voltage: Typically 5V
- Package: 14-pin PDIP (Plastic Dual-In-Line Package)
- Output Drive Capability: Capable of driving 15 LSTTL loads
- High-Speed Operation: Ensures quick data processing
Functional Description
The DM74LS164N shift register features a fully synchronous serial input to parallel output operation. Data is entered serially through a two-input AND gate synchronous with the LOW-to-HIGH transition of the clock. The device has an asynchronous clear (CLR) input that, when activated, sets all outputs low regardless of clock transitions. It does not possess an output register, which means data appears on the parallel outputs immediately after it is entered serially when the clock is active.
Applications
Due to its versatile nature, the DM74LS164N is used in a wide array of applications including:
- Serial-to-parallel data conversion
- Remote control holding registers
- Sequential operations
- Digital signal processing
- Interface circuitry
- LED and display drivers
