SN74ALS323N

Shift Registers Overview

The SN74ALS323N is an octal level-sensitive D-type flip-flop with three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range of 0°C to +70°C. The device utilizes Advanced Low-Power Schottky (ALS) TTL technology and is housed in a 20-pin Plastic Dual In-Line Package (PDIP). Key electrical characteristics include a maximum propagation delay of 16 ns at 5V with a 50pF load, a low-level output current capability of 24 mA, and a high-level output current of -2.6 mA.

Shift Registers Feature Summary

• Provides eight independent D-type flip-flops with transparent latch behavior when the clock signal is high.
• Features three-state outputs controlled by an independent output enable input for bus-oriented designs.
• Incorporates Advanced Low-Power Schottky technology to achieve high-speed operation while minimizing power consumption.

Shift Registers Applications

• Register files and buffer memory storage
• Shift registers for serial-to-parallel data conversion
• Bus-oriented logic circuits requiring isolated outputs

Shift Registers Procurement Notes

Verify that the specific order suffix matches the required package type, as variations may exist between plastic DIP and other housing options. Confirm RoHS compliance status through official manufacturer documentation, as historical production runs may differ from current specifications. Ensure the component meets the required commercial temperature grade for the intended operating environment before finalizing procurement.

Shift Registers Selection Notes

Select this component when designing systems requiring octal storage with tri-state control capabilities. The ALS series offers a balance of speed and power efficiency suitable for general-purpose digital logic applications. Consider the 20-pin PDIP footprint for prototyping or through-hole assembly requirements where surface-mount alternatives are not feasible.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74ALS family, which represents an evolution of standard 74LS logic with improved switching speeds and lower power dissipation. The SN74ALS323N specifically addresses applications needing multiple synchronized data latches with output isolation, serving as a foundational building block in complex digital system architectures.

Shift Registers Replacement Considerations

Compatible substitutes include the SN74AS323N for higher speed performance or the SN74HC323N for CMOS compatibility. Verify pinout consistency and electrical parameter alignment, particularly regarding output drive strength and supply voltage tolerance, before implementing any cross-family replacement.
