MC74VHC1GT00DFT2G

Inverter Gates Overview

The MC74VHC1GT00DFT2G is a single 2-input NAND gate from the MC74VHC1G series, manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and features TTL-level input thresholds. The device provides over-voltage tolerant inputs and outputs up to 5.5 V, enabling safe interfacing between 5 V and 3 V circuits. It supports partial power-down protection via IOFF functionality and delivers source/sink currents of 8 mA at 3.0 V. Typical propagation delay is 3.5 ns at 5 V. It is housed in an SC-88A (SC-70-5/SOT-353) package.

Inverter Gates Feature Summary

• Features TTL-level input thresholds for direct compatibility with standard logic families.
• Provides over-voltage tolerance on both inputs and outputs up to 5.5 V regardless of supply voltage.
• Supports partial power-down protection through dedicated IOFF circuitry.

Inverter Gates Applications

• Interfacing 5 V digital circuits with 3 V logic systems
• General-purpose digital signal processing applications
• Portable battery-powered electronic devices

Inverter Gates Procurement Notes

Verify that the ordering suffix matches the required package type, as the MC74VHC1G series is available in multiple configurations including SC-88A, SC-74A, SOT-953, and UDFN6. Confirm that the specific variant corresponds to the TTL threshold version (GT) rather than the CMOS threshold version (G). Ensure compliance with RoHS standards and check for automotive qualification requirements if applicable to the target application environment.

Inverter Gates Selection Notes

Select this component when a compact NAND gate with TTL-compatible inputs is required for mixed-voltage environments. The device is suitable for designs needing robust protection against supply/input voltage mismatches during hot insertion or battery backup scenarios. Consider the SC-88A package for space-constrained surface-mount layouts where small footprint is critical.

Inverter Gates Part Context

This part belongs to the MC74VHC1G family of high-speed CMOS logic gates designed for low-power applications. The 'T' designation specifically indicates TTL-level input thresholds, distinguishing it from the standard 'G' variant which uses CMOS thresholds. The 'DFT2G' suffix denotes the SC-88A package configuration with tape-and-reel shipping.

Inverter Gates Replacement Considerations

MC74VHC1G00DFT2G: Identical physical package but utilizes CMOS-level input thresholds instead of TTL levels; verify interface voltage compatibility before substitution.
