SN74AS30DBR

Overview

The SN74AS30DBR is an 8-input positive-NAND gate from the Texas Instruments 74AS series, housed in a 14-pin SSOP (DB) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range of 0°C to 70°C. Propagation delay times are specified as 1 ns to 5 ns for low-to-high transitions and 1 ns to 4.5 ns for high-to-low transitions. The device provides a high-level output current of -2 mA and a low-level output current of 20 mA.

Feature Summary

• Performs Boolean logic functions using eight inputs with a single output
• Utilizes Schottky-clamped technology for enhanced switching speed
• Designed for standard 5-V CMOS-compatible logic systems

Applications

• High-speed digital logic circuit implementations
• Data acquisition system input conditioning
• Microprocessor address decoding networks

Procurement Notes

Verify that the specific orderable part number matches the required SSOP package configuration. Confirm that the operating environment remains within the specified 0°C to 70°C temperature limits. Ensure power supply voltages do not exceed the maximum recommended ratings to maintain device reliability and prevent permanent damage during operation.

Selection Notes

Select this component when an 8-input NAND function is required alongside fast propagation delays. The SSOP package is suitable for applications prioritizing compact surface-mount board space. Consider alternative packages if higher pin counts or different thermal characteristics are necessary for the specific design constraints.

Part Context

This device belongs to the broader 74AS family of high-speed logic integrated circuits manufactured by Texas Instruments. It shares functional similarities with other members of the series but offers distinct performance metrics regarding switching speeds and drive capabilities compared to standard or low-power variants within the same logic family.
