74VCX00BQX

Inverter Gates Overview

The Fairchild Semiconductor 74VCX00BQX is a low voltage quad 2-input NAND gate IC housed in a 14-DQFN (3x2.5 mm) surface-mount package. It features inputs and outputs tolerant to 3.6V, enabling seamless interfacing between 3.3V and 5V logic systems. The device operates within a supply voltage range of 1.65V to 3.6V and supports an operating temperature range of -40°C to 85°C. Maximum propagation delay is specified at 2.8ns @ 3.3V with a 30pF load.

• Supports low voltage operation from 1.65V to 3.6V
• Designed for high-speed digital applications with low propagation delay

Inverter Gates Applications

• Mixed-voltage level translation between 3.3V and 5V logic domains
• Portable battery-powered electronic devices requiring low power consumption
• Industrial control systems operating in extended temperature environments
• Communication equipment utilizing high-speed data processing

Inverter Gates Procurement Notes

Verify the manufacturer marking on the component body matches Fairchild or ON Semiconductor branding to ensure authenticity. Confirm the package type is 14-DQFN with dimensions 3x2.5 mm. Check for any specific ordering suffixes that may indicate tape-and-reel packaging versus tube quantities. Ensure the date code aligns with current production standards if long-term availability is required.

Inverter Gates Selection Notes

Select this component when designing circuits that require logical inversion with mixed voltage levels. It is suitable for applications needing 3.6V tolerance on both input and output pins while powered by lower voltages. Consider the 14-DQFN package for space-constrained PCB layouts. Verify thermal requirements against the -40°C to 85°C operating range for your specific environment.

Inverter Gates Part Context

This part belongs to the 74VCX series, which focuses on low voltage CMOS technology. It serves as a direct replacement for older 74HC or 74HCT logic families in modern low-power designs. The BQX suffix typically denotes the specific DQFN package variant offered by Fairchild Semiconductor for surface-mount assembly processes.

Inverter Gates Replacement Considerations

The 74VCX08BQX is a documented substitute offering quad 2-input AND gates instead of NAND gates. Both share identical pinouts, packages, and electrical characteristics except for the logic function. Ensure the circuit design accommodates the inverted logic output if substituting with the 74VCX08BQX.
