DM74ALS165N

Shift Registers Overview

The DM74ALS165N is an 8-bit serial-in, parallel-out shift register manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole mounting in a 16-DIP package with a width of 0.300 inches (7.62mm). The device functions within an operating temperature range of 0°C to 70°C. It features a propagation delay of 14ns and includes parallel access to each stage for data input.

Shift Registers Feature Summary

• Provides parallel-in access to each internal stage for simultaneous data loading
• Shifts stored data toward the serial output terminal when clocked
• Configured as an 8-bit serial register compatible with TTL logic levels

Shift Registers Applications

• Parallel-to-serial data conversion circuits
• Serial-to-parallel data expansion systems
• Digital signal processing interfaces requiring bit shifting

Shift Registers Procurement Notes

Verify the component matches the specific Fairchild Semiconductor DM74ALS165N designation. Confirm the package type is 16-DIP and the electrical specifications align with the 4.5V to 5.5V supply range. Ensure the manufacturer origin is documented correctly to avoid confusion with equivalent parts from other vendors.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel load capability is required for TTL-based designs. The ALS series offers improved performance over standard LS counterparts. Consider the 16-DIP package for prototyping or applications requiring through-hole assembly methods.

Shift Registers Part Context

This part belongs to the 74ALS logic family, representing Advanced Low-power Schottky technology. It serves as a digital storage element capable of shifting binary data. The N suffix indicates the specific DIP packaging variant offered by Fairchild Semiconductor for general-purpose logic applications.

Shift Registers Replacement Considerations

Equivalent parts include the SN74ALS165 from Texas Instruments. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement supports the same 8-bit configuration and parallel load functionality.
