MC74VHC1G07DTT1

Overview

The MC74VHC1G07DTT1G is a single non-inverting buffer with an open drain output, fabricated using advanced silicon gate CMOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and features inputs/outputs over-voltage tolerant up to 5.5 V. The device provides protection against supply voltage mismatches and hot insertion. Key electrical parameters include a typical propagation delay of 3.5 ns at 5 V, source/sink current capability of 8 mA at 3.0 V, and quiescent supply current maximums of 1 µA at 25 °C and 40 µA at 125 °C.

Feature Summary

• Single non-inverting buffer configuration with open drain output structure
• Inputs and outputs are over-voltage tolerant up to 5.5 V regardless of supply voltage
• IOFF feature supports partial power down protection to prevent excessive current draw
• CMOS-level input thresholds designed for 2.0 V to 5.5 V operation

Applications

• Interfacing 5 V circuits to 3 V circuits
• Battery backup systems requiring protection against voltage mismatch
• Hot insertion applications involving supply voltage transitions
• General purpose buffering in low-power digital logic designs

Procurement Notes

Verify the complete part number includes the suffix 'DTT1G' to confirm the SC-88A package and tape & reel shipping format. Confirm RoHS compliance and Pb-free status by checking for the specific marking or documentation. Ensure the ordering code matches the required automotive or standard grade if site control changes are relevant.

Selection Notes

Select this component when a single-channel non-inverting buffer with open drain output is required. Choose this part over the MC74VHC1GT07 variant if CMOS-level input thresholds are needed rather than TTL-level thresholds. Consider the SC-88A package size constraints and verify that the 5.5 V over-voltage tolerance meets the system's I/O requirements.

Part Context

This device belongs to the MC74VHC1G07 family of single buffers. It is functionally compatible with other standard logic families while maintaining CMOS low power dissipation. The internal circuit consists of three stages including a buffer and an open drain output, allowing flexibility in setting output switching levels via external resistors.

FAQ

What is the difference between MC74VHC1G07 and MC74VHC1GT07?

The MC74VHC1G07 has CMOS-level input thresholds, whereas the MC74VHC1GT07 has TTL-level input thresholds. Both share the same open drain output structure and pinout.

How does the IOFF feature benefit the circuit?

The IOFF feature ensures that when the device is in a partial power-down state, it prevents excessive current from flowing back into the power supply through the inputs or outputs.
