74HCT3G07DC,125

Overview

The Nexperia 74HCT3G07DC,125 is a triple buffer with open-drain outputs housed in an SOT765-1 (VSSOP8) package. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device features three data inputs and corresponding open-drain outputs. Static characteristics specify a maximum low-level output voltage of 0.4 V at 4.0 mA load and 5.5 V supply. Dynamic performance includes typical propagation delays of 27 ns for OFF-state to LOW transitions and 26 ns for LOW to OFF-state transitions at 4.5 V.

Feature Summary

• Triple non-inverting buffer configuration with open-drain outputs
• TTL-compatible input switching levels for direct interfacing
• Wide operating temperature range from -40 °C to +125 °C

Applications

• Open-drain wired-OR logic implementation
• Level shifting between different voltage domains
• Driving external loads requiring pull-up resistors

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the application environment remains within the specified thermal limits. Ensure input voltages do not exceed absolute maximum ratings to prevent damage. Check for compliance with relevant regional regulatory standards prior to final design integration.

Selection Notes

Select this component when TTL logic compatibility is required alongside open-drain output capabilities. The VSSOP8 package offers space efficiency for dense layouts. Consider the power dissipation derating curves if operating near maximum ambient temperatures. Verify that the open-drain nature aligns with the downstream circuit requirements.

Part Context

This part belongs to the 74HCT series of high-speed Si-gate CMOS devices. It provides three buffers in a compact surface-mount package. The HCT designation indicates compatibility with standard TTL logic levels while maintaining CMOS power consumption characteristics. It serves as a solution for signal buffering and level translation in digital systems.

Replacement Considerations

The 74HC3G07DC,125 shares the same physical package and pinout but utilizes CMOS input levels instead of TTL. Direct substitution requires verifying that the driving source meets the higher voltage thresholds required by the HC variant.
