SN74AHCT04RGYRG4

Overview

The SN74AHCT04RGYRG4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74AHCT logic family. It features six independent inverters performing the Boolean function Y = NOT A. The device operates within a supply voltage range of 2 V to 5.5 V and supports TTL-compatible input levels, enabling direct interfacing with 5V systems while allowing level translation from 3.3V to 5V. It utilizes advanced CMOS technology for high-speed operation and low power consumption. The component is housed in a 14-VQFN package with dimensions of 3.5x3.5 mm, designed for surface-mount applications.

Feature Summary

• TTL-compatible inputs allow direct connection to 5V TTL logic levels without external pull-up resistors.
• Wide operating voltage range supports flexibility across 2V to 5.5V supply rails.
• High-speed performance ensures rapid signal inversion suitable for digital data processing.
• Robust electrostatic discharge protection meets JESD22 standards for human model and charged device model reliability.

Applications

• Level shifting interfaces between 3.3V and 5V digital logic domains
• Signal inversion in microcontroller peripheral circuits
• Clock signal conditioning in high-speed digital systems

Procurement Notes

Verify the suffix 'G4' indicates lead-free composition and RoHS compliance during sourcing. Confirm the package type matches the required PCB footprint, as the RGYR designation specifies a 14-VQFN form factor. Ensure static-safe handling procedures are followed due to the CMOS construction and sensitivity to electrostatic discharge events during assembly.

Selection Notes

Select this component when TTL input compatibility is required alongside low-power CMOS output characteristics. It is appropriate for designs needing voltage translation between 3.3V and 5V systems. Consider the 14-VQFN package constraints regarding thermal dissipation and board space. Verify that the propagation delay specifications meet the timing requirements of the target application frequency.

Part Context

This part belongs to the SN74AHCT series, which combines the speed of Advanced High-Speed CMOS with TTL-compatible inputs. It serves as a standard hex inverter solution for general-purpose digital logic applications. The RGYRG4 variant specifically denotes the tape-and-reel packaging format and lead-free manufacturing process compliant with environmental directives.

Replacement Considerations

SN74AHCT04PW: Same logical function in a TSSOP-14 package; verify pinout compatibility and thermal performance differences. SN74AHC04RGYR: Similar performance but lacks TTL input compatibility; ensure voltage levels match the source interface.
