DM74ALS576SJX

Overview

The DM74ALS576SJX is an octal D-type flip-flop manufactured by onsemi, belonging to the ALS logic series. It features eight positive-edge-triggered D flip-flops with three-state outputs in a 20-SOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a clock frequency of 30 MHz. Propagation delay is specified at 14 ns under standard conditions. Output drive capabilities include 2.6 mA high-level and 24 mA low-level currents. Static current consumption is 18 mA. The component functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Octal configuration providing eight independent positive-edge-triggered D-type storage elements.

Applications

• High-speed data buffering applications
• Parallel-to-serial conversion circuits
• Shift register implementations

Procurement Notes

This component is officially obsolete and no longer manufactured by onsemi. Verification of availability requires checking authorized distributors for remaining stock or surplus inventory. Cross-reference with equivalent parts from other manufacturers is necessary for active procurement. Ensure that any substitute components meet the specific electrical requirements and pinout compatibility before integration into existing designs.

Selection Notes

Designers should evaluate the 30 MHz maximum clock frequency and 14 ns propagation delay against system timing requirements. The 20-SOP surface-mount package necessitates appropriate PCB layout considerations for thermal management and signal integrity. Verify that the 4.5 V to 5.5 V supply voltage range aligns with the target power infrastructure. Consider the 18 mA static current draw when calculating total system power consumption.

Part Context

The DM74ALS576SJX belongs to the 74ALS family of high-speed TTL logic devices. This series offers improved performance over standard 74LS logic while maintaining compatible pinouts. The octal flip-flop architecture allows for efficient handling of wide data buses. As part of the legacy onsemi portfolio, it represents established semiconductor technology designed for robust digital logic operations in industrial and commercial environments.
