74HCT3G07GD,125

Overview

The Nexperia 74HCT3G07GD,125 is a triple buffer with open-drain outputs in an SOT996-2 package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports input voltages up to 5.5 V. The device features TTL-level input switching thresholds and includes clamp diodes on all inputs. Static characteristics specify a maximum low-level output voltage of 0.4 V at 4.0 mA load current. Dynamic performance at 4.5 V includes typical propagation delays of 11 ns for OFF-state to LOW transitions and 10 ns for LOW to OFF-state transitions.

Feature Summary

• Triple non-inverting buffer configuration with open-drain outputs
• TTL-compatible input levels for direct interfacing with standard logic families
• Input clamp diodes enable safe operation when interfacing with voltages exceeding the supply rail

Applications

• Open-drain bus line drivers
• Level shifting between different voltage domains
• Driving high-voltage loads or LEDs via external pull-up resistors

Procurement Notes

Verify the specific ordering suffix GD corresponds to the SOT996-2 package variant. Confirm that the HCT logic family requirements align with the target system's 4.5 V to 5.5 V operating voltage range. Ensure design margins account for the specified leakage currents and propagation delays under actual load conditions.

Selection Notes

Select this component when a triple buffer with open-drain capability is required for TTL-level signal processing. The inclusion of input clamp diodes makes it suitable for applications where input signals may exceed the device supply voltage. Verify that the open-drain architecture meets the system's drive requirements, as the high state relies on external pull-up components.

Part Context

This part belongs to the 74HCT series of high-speed silicon-gate CMOS devices. It provides three independent buffers within a compact surface-mount footprint. The HCT designation indicates compatibility with standard TTL logic levels while maintaining CMOS power consumption characteristics across the specified operating temperature range.

Replacement Considerations

The 74HC3G07GD,125 serves as a functional alternative if CMOS-level input thresholds are acceptable instead of TTL levels.
