SN74ALS04BDR

Overview

The SN74ALS04BDR is a hex inverter integrated circuit manufactured by Texas Instruments. It belongs to the Advanced Low-power Schottky (ALS) logic family and utilizes bipolar technology. The device features six independent inverters housed in a 14-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 11 ns, a low-level output current of 8 mA, and a high-level output current of -400 µA. The component supports surface-mount installation and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Contains six independent inverting channels for signal inversion applications.
• Utilizes Advanced Low-power Schottky (ALS) bipolar technology for performance.
• Provides TTL-compatible input levels with CMOS output characteristics.

Applications

• Signal inversion in digital logic circuits

• Waveform shaping and pulse modification

Procurement Notes

Verify the specific ordering suffix 'BDR' corresponds to the SOIC-14 package and tape-and-reel packaging configuration. Confirm that the ALS logic series meets the required speed and power constraints for the target design. Ensure compatibility with standard 5V logic systems given the specified voltage range. Check for RoHS compliance status as indicated in official documentation before finalizing procurement.

Selection Notes

Select this component when a hex inverter with moderate speed and low power consumption is required. The ALS series offers a balance between speed and power dissipation compared to standard or LS families. The SOIC-14 package is suitable for surface-mount assembly processes. Verify that the 8 mA sink capability and -400 µA source capability meet the load requirements of the connected circuitry.
