SN74ACT04BQAR

Overview

The SN74ACT04BQAR is a hex inverter manufactured by Texas Instruments, belonging to the 74ACT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides six independent inverting channels with low quiescent current consumption. It supports output drive currents of up to 24 mA for both high and low states. The component is housed in a WQFN-14 package and is rated for an operating temperature range from -40°C to +125°C.

Feature Summary

• Hex inverter configuration providing six independent signal inversion channels
• TTL-compatible input thresholds ensuring compatibility with standard logic families
• Low power consumption characteristics typical of CMOS technology
• Extended industrial temperature rating suitable for harsh environments

Applications

• Signal inversion in digital logic circuits
• Clock signal conditioning and buffering
• Level shifting between different logic domains
• General-purpose switching applications in embedded systems

Procurement Notes

Verify the specific suffix 'BQA' against the official Texas Instruments datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the ordering part number matches the required RoHS compliance status and manufacturing date code. Cross-reference the manufacturer's latest documentation to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a compact hex inverter solution is required for space-constrained designs. The ACT series offers faster propagation delays compared to standard AC devices while maintaining lower power consumption than ALS variants. Consider the WQFN-14 package for surface-mount assembly requirements. Verify that the 5V supply voltage aligns with the system's power rails and that the thermal performance meets the application's heat dissipation needs.

Part Context

This component is part of the broader 74ACT family of high-speed CMOS logic devices produced by Texas Instruments. The family includes various logic functions such as gates, flip-flops, and buffers. The SN74ACT04 specifically addresses the need for multiple inverting stages in a single package, reducing board space and interconnect complexity in digital circuit designs.

Replacement Considerations

Compatible substitutes include other hex inverters from the 74ACT series, such as the SN74ACT04DR or SN74ACT04PW, provided the package footprint is compatible. Ensure that any replacement maintains the same voltage range and pinout configuration to guarantee functional equivalence without requiring PCB redesign.
