SN74ALS992DWR

Overview

The SN74ALS992DWR is a D-type transparent latch from the Texas Instruments ALS logic series, housed in a 24-SOIC surface-mount package. It features nine independent channels with tri-state outputs and operates within a supply voltage range of 4.5V to 5.5V. The component exhibits a propagation delay of 6ns, with output currents specified at 400µA for high state and 8mA for low state. It supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Provides nine-channel data storage via D-type transparent latching mechanism
• Integrates tri-state outputs for effective bus line management
• Utilizes Advanced Low-Power Schottky (ALS) technology for optimized performance

Applications

• Parallel data buffering in digital systems
• Temporary data storage within processing architectures
• Interface control circuits requiring tri-state isolation

Procurement Notes

Verify current availability status as this specific part number may be obsolete or discontinued. Confirm that the required tape and reel packaging aligns with automated assembly equipment specifications. Ensure compatibility with RoHS3 standards if environmental compliance is mandatory for the target deployment environment.

Selection Notes

Select this component when nine-bit parallel latching with tri-state capability is required within the ALS family constraints. Consider the 6ns propagation delay and 4.5V to 5.5V operating voltage against system timing and power requirements. Evaluate the 24-SOIC footprint against available PCB real estate and thermal dissipation needs.

Part Context

This device belongs to the SN74ALS992 product family, designed for high-speed digital applications requiring reliable data retention. The ALS series offers a balance between speed and power consumption, making it suitable for complex logic designs where multiple latch channels are necessary for efficient data handling and synchronization.
