74VHCT04ASJX

Inverter Gates Overview

The Fairchild Semiconductor 74VHCT04ASJX is a high-speed CMOS hex inverter belonging to the 74VHCT series. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible inputs. The device contains six independent inverters, each with a single input, housed in a 14-pin Small Outline Package (SOP). Key electrical specifications include a maximum static supply current of 2 µA and output currents of 8 mA for both high and low states. Propagation delay is specified at 7.7 ns under conditions of 5V supply voltage and 50 pF load capacitance. The component supports an operating temperature range from -40°C to 85°C.

Inverter Gates Feature Summary

• High-speed CMOS technology providing performance comparable to equivalent bipolar Schottky TTL while maintaining low power dissipation.
• TTL-compatible input logic levels allow direct interfacing with standard digital systems without additional level shifting.
• Provides balanced propagation delays across all channels for consistent signal inversion timing.

Inverter Gates Applications

• General-purpose signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Data bus line drivers requiring high-speed switching

Inverter Gates Procurement Notes

Verify the exact package dimensions and pinout against the official datasheet before integration, as SOP variants may differ slightly in width. Confirm that the 7.7 ns propagation delay meets system timing requirements under your specific load and voltage conditions. Ensure ESD handling protocols are followed during assembly due to the CMOS construction. Check for RoHS compliance status if required by your manufacturing standards.

Inverter Gates Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed CMOS performance. It serves as a suitable replacement for older HCT series devices where faster switching speeds are needed. Consider the 14-SOP package constraints regarding PCB space and thermal management. Evaluate the 8 mA drive capability against the fan-out requirements of the connected loads.

Inverter Gates Part Context

This part belongs to the 74VHCT family, which bridges the gap between standard CMOS and TTL logic families. The VHCT series is designed to offer higher speed than standard HCT parts while retaining full compatibility with TTL input thresholds. This specific model represents the hex inverter configuration, a fundamental building block in digital electronics used for logical negation and signal buffering.
