SN74ALS323N3

Shift Registers Overview

The SN74ALS323N is an 8-bit universal shift/storage register from the Texas Instruments ALS logic family. It features multiplexed I/O ports for full 8-bit data handling within a 20-pin package. The device supports four modes: Hold, Shift Right, Shift Left, and Load Data. It includes synchronous parallel loading, synchronous clearing, and 3-state outputs that can drive bus lines directly. The SN74ALS323 operates with a supply voltage of 4.5 V to 5.5 V and is characterized for temperatures from 0°C to 70°C.

Shift Registers Feature Summary

• Multiplexed input/output ports enable efficient 8-bit data handling in a compact 20-pin package.
• Supports four distinct operational modes including hold, shift right, shift left, and synchronous parallel load.
• Features 3-state outputs capable of driving bus lines directly while allowing high-impedance isolation.

Shift Registers Applications

• Stacked or push-down registers
• Buffer storage applications
• Accumulator registers

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm the exact physical package type and material specifications. Ensure the selected variant matches the required operating temperature range and RoHS compliance status for your application environment.

Shift Registers Selection Notes

Select this component when designing systems requiring versatile serial-to-parallel or parallel-to-serial conversion capabilities. The multiplexed I/O architecture reduces pin count requirements compared to standard shift registers. Consider the 3-state output feature if direct bus interfacing is necessary for system integration.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74ALS series, which utilizes Advanced Low-power Schottky technology. The SN74ALS323 serves as a catalog version of the military-grade SN54ALS323, differing primarily in the specified operating temperature range. It is designed for general-purpose digital logic applications requiring reliable shift and storage functions.

Shift Registers Replacement Considerations

The SN74ALS323N is the commercial catalog equivalent of the SN54ALS323J. Verify compatibility regarding the operating temperature range, as the SN54 variant supports -55°C to 125°C while the SN74 variant is rated for 0°C to 70°C.
