SN74ALS996NT

Overview

The SN74ALS996NT is an octal D-type edge-triggered latch with read-back capability from the Texas Instruments ALS logic family. 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 a commercial operating temperature range from 0°C to +70°C.

Feature Summary

• Octal configuration providing eight independent D-type latches in a single integrated circuit
• Edge-triggered operation synchronized by clock signals for precise data capture
• Read-back functionality allowing direct monitoring of internal latch states via dedicated outputs

Applications

• High-speed parallel-to-serial data conversion systems
• Buffering and temporary storage of digital data streams
• Interface circuits between microprocessors and peripheral devices

Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued or obsolete. Confirm that the specific suffix matches required packaging and temperature ratings. Review the official datasheet for absolute maximum ratings and thermal management requirements before integration into final designs.

Selection Notes

Select this component when designing systems requiring simultaneous storage of multiple bits with immediate state visibility. Ensure the design accommodates the specified 5V logic levels and current drive capabilities. Consider the SOIC-24 footprint constraints and verify compatibility with existing board layout and signal integrity standards.

Part Context

This device belongs to the SN74ALS996 series, representing Texas Instruments' Advanced Low-power Schottky logic technology. The series is engineered for high-speed performance while maintaining lower power consumption compared to standard TTL equivalents. The SN74ALS996 variant specifically addresses applications needing wide data bus handling with read-back diagnostics.

Replacement Considerations

Consult official cross-reference documentation for verified substitutes. Ensure any replacement maintains identical pinout, logic function, and electrical characteristics to guarantee system compatibility without hardware modification.
