MC74VHC1G14DTT1

Inverter Gates Overview

The MC74VHC1G14DTT1 is a single Schmitt-trigger inverter from the 74VHC 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 high noise immunity through buffered output structures and includes 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. The component is housed in a SC-88A (SC-70-5/SOT-353) surface-mount package with five pins.

Inverter Gates Feature Summary

• Schmitt-trigger input action for improved noise immunity
• Over-voltage tolerant I/O structures up to 5.5 V
• Partial power-down protection capability
• High drive current capability

Inverter Gates Applications

• Signal conditioning and waveform shaping
• Oscillator circuits
• Timing pulse generation
• Level shifting between different voltage domains

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DTT1' corresponds to the SC-88A package and tape-and-reel shipping configuration. Confirm that the '-Q' suffix is not required if automotive qualification or unique site control changes are necessary for the application. Ensure compliance with RoHS and halogen-free requirements as stated in the datasheet.

Inverter Gates Selection Notes

Select this component when a single inverter with Schmitt-trigger inputs is needed for noisy environments. Choose the VHC series for higher speed and lower power consumption compared to standard HC logic. Consider the SC-88A package for compact board space requirements. Verify that the 5.5 V over-voltage tolerance meets the interface requirements between 3 V and 5 V systems.

Inverter Gates Part Context

This part belongs to the MC74VHC1G14/MC74VHC1GT14 family of single Schmitt-trigger inverters. The 'VHC' designation indicates Very-High-Speed CMOS technology. The 'T' in the model number typically denotes the SC-88A package variant. The device is designed for portable and battery-operated applications due to its low power consumption and wide operating voltage range.

Inverter Gates Replacement Considerations

Direct replacements include MC74VHC1G14DBVT1G (SC-74A package) and MC74VHC1G14DFT1G (standard SC-88A). Cross-manufacturer equivalents such as Diodes Incorporated's 74AHC1G14W5-7 may be considered, but verify pinout compatibility and electrical characteristics.
