SN74AHCT1G00DCK3

Overview

The SN74AHCT1G00DCK3 is a single 2-input positive NAND gate from Texas Instruments, belonging to the AHCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible CMOS inputs. The device provides a low-level output current of 8 mA and a high-level output current of -8 mA. Propagation delay is specified at 7.1 ns. It is housed in a SC-70-5 (DCK) package with five pins and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• TTL-compatible CMOS inputs for direct interface with TTL logic systems
• Single-channel architecture containing one independent 2-input NAND gate
• High noise immunity characteristics inherent to the AHCT logic family

Applications

• Digital signal processing circuits requiring NAND logic functions
• Microcontroller input/output expansion and interfacing
• Memory address decoding and control logic generation

Procurement Notes

Verify the complete part number including the DCK3 suffix to ensure the correct SC-70-5 package and tape-and-reel quantity configuration. Confirm that the system power supply remains strictly within the 4.5 V to 5.5 V range to maintain valid logic levels. Ensure thermal management aligns with the -40°C to 85°C industrial operating temperature specification during installation.

Selection Notes

Select this component when TTL compatibility is required alongside CMOS performance standards. The AHCT series bridges the gap between older TTL systems and modern CMOS designs. The SC-70-5 package offers space efficiency for dense PCB layouts. Verify that the 7.1 ns propagation delay meets the timing constraints of the target digital circuit design.

Part Context

This component belongs to the SN74AHCT1Gxx family of single-gate integrated circuits. It shares the same logical function as the SN74AHCT1G00DCKR but differs in packaging format. The DCK3 designation specifically identifies the SC-70-5 surface-mount variant. This family provides compact solutions for basic logic operations in portable and industrial electronics.

Replacement Considerations

The SN74AHCT1G00DCKR serves as a functional substitute with identical electrical specifications, differing primarily in reel packaging configuration.
