74LCX04TTR

Inverter Gates Overview

The 74LCX04TTR is a low-voltage CMOS hex inverter manufactured with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a supply voltage range of 2.0V to 3.6V, featuring 5V tolerant inputs that allow interfacing with 5V signal environments. The device provides high-speed performance with a maximum propagation delay of 5.2ns at VCC = 3V. It includes power-down protection on all inputs and outputs, symmetrical output impedance with |IOH| = IOL = 24mA (min) at VCC = 3V, and balanced propagation delays where tPLH is approximately equal to tPHL.

Inverter Gates Feature Summary

• Features 5V tolerant inputs for direct interfacing with 5V signal environments while operating at lower voltages.
• Provides high-speed logic inversion with balanced propagation delays suitable for demanding timing applications.
• Includes power-down protection on both inputs and outputs to prevent excessive current draw during power-off states.

Inverter Gates Applications

• Low-power and high-speed 3.3V digital logic applications
• Interfacing between 5V signal environments and 3.3V logic circuits
• Line receivers requiring stable output inversion

Inverter Gates Procurement Notes

Verify the specific package type required for your design, as the 74LCX04 series is available in multiple configurations including TSSOP-14 and SOP-14. Confirm that the ordering suffix matches the desired packaging format, such as tape and reel for surface-mount assembly. Ensure compatibility with your board layout constraints regarding footprint dimensions and pin pitch specifications before finalizing procurement.

Inverter Gates Selection Notes

Select this component when designing systems that require robust interface capabilities between different voltage domains, specifically bridging 5V inputs to 3.3V logic cores. The device is appropriate for applications prioritizing low power consumption alongside high switching speeds. Consider its ESD immunity and latch-up performance for environments susceptible to electrostatic discharge or transient voltage spikes.

Inverter Gates Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices from STMicroelectronics. The LCX series is engineered to offer speed performance comparable to older 5V AC/ACT families but with significantly reduced power consumption. It serves as a modern replacement for legacy logic components in portable and battery-operated electronic equipment requiring efficient power management.

Inverter Gates Replacement Considerations

Direct functional replacements include other 74LCX04 variants from different manufacturers that maintain pin compatibility. Verify that substitute parts support the same 5V input tolerance and operate within the 2.0V to 3.6V supply range. Ensure any alternative maintains similar propagation delay characteristics and output drive strength for circuit integrity.
