MC74VHC1G07DBVT1G

Overview

The MC74VHC1G07DBVT1G is a single non-inverting buffer with an open drain output, manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and features CMOS-level input thresholds. The device provides high-speed operation with a typical propagation delay of 3.5 ns at 5 V. It supports partial power down protection via IOFF and includes over-voltage tolerant inputs and outputs up to 5.5 V. The component is housed in a SC-74A (SC-74A-5) surface-mount package.

Feature Summary

• Single non-inverting buffer with open drain output structure
• Inputs and outputs tolerant to voltages up to 5.5 V regardless of supply voltage
• Supports partial power down protection through IOFF feature
• High-speed operation with low internal power dissipation

Applications

• Interfacing 5 V circuits to 3 V circuits
• Battery backup systems requiring voltage mismatch protection
• Hot insertion applications

Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping configuration. Ensure the part number matches the required logic family and output structure for your design. Confirm RoHS compliance and lead-free status if environmental regulations apply. Check for automotive qualification requirements if the application demands AEC-Q100 standards.

Selection Notes

Select this component when a compact single-channel buffer with open drain capability is needed. It is suitable for designs requiring interface between different voltage domains, specifically 5 V to 3 V systems. Consider the SC-74A package size for space-constrained PCB layouts. Verify that the open drain output meets the pull-up requirements of the destination circuit.

Part Context

This device belongs to the MC74VHC1G series of advanced high-speed CMOS logic components. It is fabricated using silicon gate CMOS technology to achieve performance similar to Bipolar Schottky TTL while maintaining low power consumption. The series includes variants with different input threshold levels, such as TTL-compatible options.

Replacement Considerations

MC74VHC1GT07DBVT1G offers identical functionality but with TTL-level input thresholds instead of CMOS-level. Other single-buffer devices from the same manufacturer may provide different package options or drive strengths.
