74ABT373CPC

Overview

The DM74LS373SJX is an octal transparent latch with three-state outputs manufactured by onsemi/Fairchild. It operates within a supply voltage range of 4.75 V to 5.25 V and features a propagation delay of 27 ns at 5 V. The device provides a high-level output current of -2.6 mA and draws a working power supply current of 40 mA. It supports eight input lines and eight output lines in a single circuit configuration. The component is housed in an SOP-II package suitable for SMD/SMT installation and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Provides tri-state outputs for bus interfacing applications
• Features eight latches in a single package
• Ensures non-destructive hot insertion capability

Applications

• Bus organized system applications
• Bus interfacing

Procurement Notes

Verify the specific manufacturer designation, as the part number may be associated with either onsemi or Fairchild Semiconductor due to corporate history. Confirm the package type matches the required SOP-II form factor and ensure the operating temperature range meets the application's environmental constraints. Check for any specific ordering suffixes that might indicate packaging variations such as reel formats.

Selection Notes

Select this component when an octal latch with tri-state control is required for bus-oriented designs. Ensure the logic family compatibility aligns with the system's voltage levels and speed requirements. Consider the package style and thermal performance if the application involves higher ambient temperatures or dense PCB layouts.

Part Context

This component belongs to the 74ABT series of octal transparent latches with tri-state outputs. It is designed for bus-organized system applications where data retention and high-impedance states are necessary. The device is compatible with standard military drawing specifications and offers guaranteed latchup protection.

Replacement Considerations

Public confirmed substitute part numbers include 74ABT373CSC and 74ABT373CSJ.
