74HCT3G04DC,125

Inverter Gates Overview

The Nexperia 74HCT3G04DC,125 is a triple inverter housed in an 8-lead VSSOP package (SOT765-1). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels, CMOS low power dissipation, and high noise immunity. Static characteristics include an input leakage current maximum of ±1.0 μA at 5.5 V and an additional supply current per input pin maximum of 410 μA. Dynamic performance specifies a propagation delay maximum of 29 ns at 4.5 V.

Inverter Gates Feature Summary

• Provides three independent inverting logic gates within a compact surface-mount footprint.
• Features Schmitt-trigger action for improved noise immunity and tolerance to slow input transitions.
• Includes internal clamp diodes on inputs to facilitate interfacing with voltages exceeding the supply rail.

Inverter Gates Applications

• Signal inversion in digital logic circuits
• Waveform shaping and pulse generation
• Clock signal conditioning

Inverter Gates Procurement Notes

Verify the specific ordering suffix '125' corresponds to the VSSOP-8 (SOT765-1) package variant. Confirm that the HCT logic family aligns with the target system's TTL-compatible input requirements. Ensure design margins account for the specified operating temperature range up to +125 °C and verify compliance with relevant RoHS directives prior to final procurement.

Inverter Gates Selection Notes

Select this component when a triple inverter function is required with TTL-compatible input thresholds. The VSSOP-8 package offers space efficiency for dense PCB layouts. Consider the 4.5 V to 5.5 V supply constraint and ensure the application does not require the wider voltage range available in HC or LVC variants. Evaluate thermal derating requirements if operating near the upper temperature limit.

Inverter Gates Part Context

This part belongs to the Nexperia 74HCT series of high-speed silicon-gate CMOS devices. It shares the same physical package and pinout as the 74HC3G04 but utilizes different input switching levels compatible with TTL standards. The DC suffix specifically denotes the very thin shrink small outline plastic package configuration.

Inverter Gates Replacement Considerations

The 74HC3G04DC,125 serves as a pin-compatible alternative but requires CMOS-level input signals rather than TTL levels. Other triple inverters in the VSSOP-8 package may be considered if voltage ranges or speed characteristics differ from these specifications.

Inverter Gates FAQ

What is the difference between the 74HCT3G04 and 74HC3G04?

The primary difference lies in the input logic levels. The 74HCT3G04 accepts TTL-level inputs, whereas the 74HC3G04 requires CMOS-level inputs. Both share identical pinouts and package types.

How do the input clamp diodes function?

The inputs include clamp diodes that allow the use of current-limiting resistors. This enables the device to interface with input voltages that exceed the supply voltage (VCC) without damage, provided current limits are observed.
