SN74ALS04BDB

Overview

The SN74ALS04BDB is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the Advanced Low-power Schottky (ALS) logic family. It features six independent inverters within a single package. The device operates on a bipolar logic type and is housed in an SSOP-14 surface-mount package. It supports a supply voltage range of 4.5 V to 5.5 V and functions within a commercial temperature range of 0°C to +70°C. Key electrical characteristics include a propagation delay of 11 ns, a low-level output current of 8 mA, and a high-level output current of -400 µA.

Feature Summary

• Integrates six independent inverter channels for signal inversion within a compact surface-mount package.
• Utilizes Advanced Low-power Schottky technology to achieve TTL-compatible speeds with reduced power consumption compared to standard LS series devices.
• Features bipolar input types compatible with standard TTL logic levels.

Applications

• General-purpose digital signal inversion in computer systems.
• Clock signal generation and conditioning circuits.
• Buffering applications in industrial control logic.

Procurement Notes

Verify the specific package variant upon ordering, as the 'DB' suffix typically denotes an SSOP-14 package, which differs from the SOIC-14 package associated with the 'D' suffix. Confirm that the ALS logic family meets the system's power and speed requirements before procurement. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability.

Selection Notes

Select this component when a balance between moderate speed and lower power dissipation is required compared to standard 74LS logic. It serves as a direct functional replacement for other hex inverters like the SN74LS04 or SN74ALS04, provided the SSOP-14 footprint is acceptable. Consider the 11 ns propagation delay and 8 mA drive capability against the specific load requirements of the target application circuit.

Part Context

This part belongs to the Texas Instruments SN74ALS04 series, which represents the Advanced Low-power Schottky logic family. This family was designed to offer performance improvements over the standard 74LS series while maintaining pin compatibility and logical functionality. The hex inverter configuration is a fundamental building block in digital electronics, widely used across various computing and communication hardware platforms.

Replacement Considerations

The SN74ALS04BD is a verified substitute part number offering identical functionality in a standard SOIC-14 package instead of the SSOP-14 format. Other compatible alternatives within the same logic family include the SN74ALS04DR and SN74ALS04N, depending on the required mounting style and package geometry.
