74LCX00SJX

Inverter Gates Overview

The onsemi 74LCX00SJX is a low-voltage CMOS quad dual-input NAND gate manufactured using sub-micron silicon gate and double-layer metal wiring C2 MOS technology. It operates within a supply voltage range of 2.0 V to 3.6 V, providing high-speed performance comparable to the 5 V AC/ACT family while maintaining lower power consumption. The device features 5 V tolerant inputs, allowing direct interfacing with 5 V signal environments. All inputs and outputs include protection circuits against static discharge, ensuring robust immunity to ESD events.

Inverter Gates Feature Summary

• Features 5 V tolerant inputs for seamless interfacing between 3.3 V logic and 5 V signal environments
• Provides high-speed operation with symmetrical output impedance and balanced propagation delay characteristics
• Includes power-down protection on inputs and outputs to prevent excessive current draw during low-power states
• Offers enhanced ESD immunity with protection circuits rated for significant transient excess voltage

Inverter Gates Applications

• Low-power and high-speed 3.3 V digital applications
• Interfacing 5 V systems to 3 V systems
• PCI bus level applications requiring guaranteed performance at specific drive currents

Inverter Gates Procurement Notes

Verify the exact suffix 'SJX' against official manufacturer documentation, as standard listings often use 'SJ'. Confirm package type (SOP-14) and temperature range (-40°C to 85°C). Ensure the component meets required AEC-Q100 or other automotive qualifications if applicable, as these vary by specific manufacturing lot and suffix designation.

Inverter Gates Selection Notes

Select this component when designing low-voltage digital circuits requiring quad NAND functionality with 5 V input tolerance. It is suitable for applications needing high speed at 3.3 V with reduced power dissipation compared to older 5 V families. Consider the 14-SOP package constraints and ensure the operating temperature range aligns with the system environment.

Inverter Gates Part Context

This part belongs to the 74LCX series, which represents low-voltage CMOS technology designed for high-speed, low-power applications. The LCX series is pin-compatible with earlier 74 series logic but optimized for modern 3.3 V and 2.5 V supply voltages. It serves as a drop-in replacement for many legacy 5 V logic functions in new low-voltage designs.
