SN74AS804BDWR

Overview

The SN74AS804BDWR is a Texas Instruments integrated circuit containing six independent 2-input NAND drivers. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of 0°C to 70°C. The device features high capacitive-drive capability with a maximum low-level output current of 48mA and a maximum high-level output current of -48mA. Propagation delay times are specified between 1ns and 5ns under standard load conditions.

Feature Summary

• Contains six independent 2-input NAND logic gates
• Provides high capacitive-drive capability for demanding loads
• Supports operation across the commercial temperature range

Applications

• High-speed digital logic circuits
• Memory systems requiring fast switching
• Microprocessor-based control interfaces

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the datasheet indicates availability in tubes. Confirm the component status against official manufacturer records, as product lifecycles change. Ensure the procurement channel provides valid traceability documentation for catalog-grade parts.

Selection Notes

Select this component when high-speed NAND functionality is required alongside significant drive strength. Compare propagation delays and power dissipation against system timing constraints. Verify that the SOIC-20 surface-mount package aligns with the printed circuit board layout requirements.

Part Context

This part belongs to the Texas Instruments 74AS series of advanced Schottky logic devices. The 'B' designation identifies it as the higher-performance variant within the AS family compared to the ALS series. It utilizes a plastic small-outline (DW) package configuration suitable for automated surface-mount assembly processes.

Replacement Considerations

SN74AS804BDW is available in tube packaging.
