SN74ALS996NTG4

Overview

The SN74ALS996NTG4 is an octal D-type edge-triggered latch with read-back functionality manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 28 ns. The device provides a low-level output current of 32 mA and a high-level output current of -2.6 mA, with a typical operating supply current of 85 mA. Designed for surface-mount applications, it is housed in a SOIC-24 package and supports non-inverting logic operations across eight channels.

Feature Summary

• Provides read-back capability for internal data verification
• Features octal configuration for parallel data handling
• Utilizes edge-triggered operation for precise timing control

Applications

• Parallel data storage systems
• High-speed digital buffering
• Read-back verification circuits

Procurement Notes

Verify the specific suffix 'NTG4' against official manufacturer documentation to confirm lead-free status and RoHS compliance details. Confirm availability as this component may be discontinued or subject to limited production runs. Ensure the SOIC-24 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when octal latching with read-back is required in ALS speed grades. Compare performance metrics such as the 28 ns propagation delay against system timing constraints. Evaluate the 32 mA low-level output drive capability against load requirements. Verify that the 4.5 V to 5.5 V operating voltage aligns with the target power supply architecture.

Part Context

This part belongs to the SN74ALS996 series of octal D-type latches. It is part of the Advanced Low-power Schottky (ALS) logic family, which offers improved speed and power consumption characteristics compared to standard LS logic. The device is designed for high-density digital applications requiring reliable data storage and retrieval.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical specifications before replacing the component.
