DM74ALS374SJ

Overview

The DM74ALS374SJ is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ALS logic series. It features positive-edge triggering and three-state non-inverting outputs. The component operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 35 MHz. Propagation delay is specified at 16ns under standard load conditions. It is housed in a 20-SOP package with a width of 5.30mm and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Positive-edge triggered operation ensures data capture occurs precisely at the rising edge of the clock signal.
• Three-state outputs allow direct connection to bus systems without requiring additional interface components.

Applications

• Implementation of buffer registers in digital systems
• Construction of I/O ports for microprocessor interfaces
• Design of bidirectional bus drivers
• Utilization as working registers in data processing circuits

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the part number matches DM74ALS374SJ exactly, including suffix designations. Check datasheet revisions for any updates regarding pinout or electrical characteristics. Ensure compliance with RoHS directives if required for the specific application environment.

Selection Notes

Select this component when an octal storage element with high-speed performance is required. The ALS series offers improved switching speeds compared to standard LS logic while maintaining compatible power consumption levels. Consider the 20-SOP package size for surface-mount assembly constraints. Verify that the three-state output capability aligns with the system's bus architecture requirements.

Part Context

This device is part of the broader 74ALS family of logic integrated circuits produced by onsemi. The 74ALS series represents an advanced low-power Schottky technology variant designed for applications demanding faster switching times than traditional TTL logic. The DM74ALS374SJ specifically addresses needs for multi-bit data storage and transfer in complex digital designs.

Replacement Considerations

SN74ALS374ANSR from Texas Instruments serves as a direct substitute. SN74ALS374ADW and SN74ALS374ADWR are also listed as similar alternatives. These replacements maintain functional compatibility within the 74ALS logic family specifications.
