SN74ALS04BNSR

Overview

The SN74ALS04BNSR is a hex inverter integrated circuit from the Texas Instruments SN74ALS04B series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels with CMOS output characteristics. The device features six independent inverting circuits housed in a 14-pin SOIC package. 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. It functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Contains six independent inverting logic channels for signal inversion applications.
• Provides compatibility between TTL input logic levels and CMOS output drive capabilities.
• Delivers fast switching performance with a specified propagation delay of 11 ns.

Applications

• Digital signal inversion in bus interface circuits
• Clock signal generation and conditioning
• Logic level translation between TTL and CMOS domains

Procurement Notes

Verify the specific ordering suffix 'NSR' to confirm the SOIC-14 package type and tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the ALS logic family specifications align with your system's power and speed constraints before finalizing procurement.

Selection Notes

Select this component when designing systems requiring hex inverters with ALS speed and power characteristics. It is suitable for applications needing TTL-compatible inputs driving CMOS loads. Consider the 14-pin SOIC package dimensions for PCB layout and verify that the 4.5V to 5.5V supply range matches your design's power architecture.

Part Context

This part belongs to the Texas Instruments SN74ALS04B series, which utilizes Advanced Low-power Schottky (ALS) technology. The series provides faster switching speeds than standard LS logic while maintaining lower power consumption than AS logic. The SN74ALS04BNSR specifically denotes the surface-mount reel version of this hex inverter.

Replacement Considerations

Publicly confirmed substitutes include SN74ALS04BDR and SN74ALS04BNSR. Verify pinout compatibility and electrical specifications before substitution.
