74LCX32SJX

Inverter Gates Overview

The onsemi 74LCX32SJX is a quad 2-input OR gate integrated circuit manufactured using advanced LCX/LVC-CMOS technology. It operates within a supply voltage range of 1.65V to 3.6V, ensuring compatibility with low-voltage digital systems. The device features high-speed performance with propagation delays as low as 4.9ns at 3.3V and supports output drive currents up to 24mA. Packaged in a 14-SOP format, it includes IOFF support for partial power-down applications, preventing backflow current during system shutdowns.

Inverter Gates Feature Summary

• Provides four independent 2-input OR logic gates in a single package
• Supports mixed-voltage environments with 5.5V tolerant inputs
• Includes IOFF circuitry to disable outputs and prevent damaging backflow current when powered down
• Operates reliably across an extended temperature range from -40°C to 85°C

Inverter Gates Applications

• Mixed-voltage signal routing between different logic domains
• Partial power-down mode implementations requiring safe state isolation
• Low-voltage portable electronic devices and battery-operated equipment
• High-speed data bus arbitration and control logic circuits

Inverter Gates Procurement Notes

Verify the exact suffix SJX against official datasheets to confirm package dimensions and pinout compatibility. Ensure the component meets RoHS and REACH compliance requirements for your specific region. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the operating voltage range aligns with your system's power supply specifications before integration.

Inverter Gates Selection Notes

Select this component when designing systems requiring low voltage operation combined with high-speed switching capabilities. The LCX series offers superior performance compared to standard HC logic while maintaining CMOS low power consumption. Consider the 14-SOP package size for space-constrained PCB layouts. Verify input tolerance levels if interfacing with 5V signals to ensure reliable logic level translation without external components.

Inverter Gates Part Context

This device belongs to the 74LCX family of low-voltage CMOS logic ICs, designed for high-speed applications. It serves as a direct replacement for older 74HC or 74LVC counterparts in many designs, offering improved speed and lower power dissipation. The OR gate function is fundamental in digital logic design, making this component widely used in microcontroller interfaces and memory address decoding circuits.

Inverter Gates Replacement Considerations

Direct substitutes include other manufacturers' 74LCX32 variants in SOP-14 packages. Verify pin compatibility and electrical characteristics such as propagation delay and output drive strength. Check for equivalent IOFF functionality if partial power-down support is required in the target application.
