SN74AHCT00RGYR

Overview

The SN74AHCT00RGYR is a quad 2-input NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the 74AHCT logic series, designed for high-speed CMOS operation with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum propagation delay of 7.9 ns at 5 V with a 50 pF load. It provides symmetric output drive currents of 8 mA for both high and low states. The component is housed in a 14-VQFN package measuring 3.5x3.5 mm and supports surface-mount installation.

Feature Summary

• TTL-compatible input thresholds enable direct interfacing with legacy TTL logic systems while maintaining CMOS performance characteristics.
• High-speed switching capability ensures rapid signal processing with minimal propagation delay for time-critical digital applications.
• Robust output drive strength supports multiple loads and maintains signal integrity across standard digital bus architectures.

Applications

• Digital signal processing circuits requiring fast logical operations
• Microcontroller peripheral interface logic
• Memory address decoding networks
• Automotive electronic control unit logic gates

Procurement Notes

Verify the specific suffix RGYR corresponds to the 14-VQFN 3.5x3.5mm package configuration. Confirm AEC-Q100 qualification status if automotive reliability standards are required for the target application environment. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Selection Notes

Select this component when TTL-level compatibility is necessary alongside high-speed CMOS performance. The 14-VQFN package offers a compact footprint suitable for space-constrained designs. Verify that the 4.5V to 5.5V operating range aligns with the system power supply rails before integration into the schematic.

Part Context
