SN74AHCT04RGYR

Overview

The SN74AHCT04RGYR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74AHCT logic family. It features six independent inverters housed in a 14-VQFN package with exposed thermal pad. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports input levels compatible with standard CMOS and TTL outputs. Key electrical specifications include a propagation delay of 5.5 ns, high-level output current of -8 mA, and low-level output current of 8 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Hex inverter configuration providing six independent signal inversion channels
• TTL-compatible inputs allowing direct interfacing with TTL-driven systems
• CMOS outputs ensuring low power consumption and high noise immunity
• Exposed thermal pad design for enhanced heat dissipation in surface-mount applications

Applications

• Signal inversion in digital logic circuits
• Clock signal conditioning and buffering
• Interface between TTL and CMOS logic domains
• Waveform shaping and pulse generation

Procurement Notes

Verify the specific suffix RGYR corresponds to the 14-VQFN package with exposed pad and tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure moisture sensitivity level (MSL) handling requirements are met during storage and assembly processes. Cross-reference the full part number against the latest Texas Instruments product selection guide to confirm availability and lifecycle status.

Selection Notes

Select this component when designing 5V logic systems requiring TTL-compatible inputs with CMOS output characteristics. The AHCT series is suitable for applications needing moderate speed performance with low power consumption. Consider the 14-VQFN package for space-constrained PCB layouts requiring efficient thermal management via the exposed pad. Verify that the required propagation delay and drive current meet the system's timing and load requirements.

Part Context

This part belongs to the Texas Instruments 74AHCT logic family, which combines the low power consumption of CMOS technology with TTL-compatible input thresholds. The 'H' denotes high-speed operation relative to standard 74HC devices, while 'CT' indicates TTL compatibility. The 'AUC' or 'AHCT' prefix signifies advanced technology nodes optimized for 5V operation. This specific model provides hex inversion functionality within a compact surface-mount footprint.

Replacement Considerations

Check for equivalent parts such as SN74AHCT04DR or SN74AHCT04DCK from Texas Instruments, ensuring pinout and package compatibility. Other manufacturers may offer functionally similar hex inverters, but verify voltage ranges, input/output characteristics, and package dimensions before substitution.
