74LV27D,118

Inverter Gates Overview

The 74LV27D,118 is a triple 3-input NOR gate manufactured by Nexperia (formerly Philips Semiconductors). It operates within a supply voltage range of 1.0 V to 5.5 V and is optimized for low-voltage applications between 1.0 V and 3.6 V. The device accepts TTL input levels when the supply voltage is between 2.7 V and 3.6 V. It features standard output capability with typical VOLP of 2 V at 3.3 V. Propagation delay is typically 8 ns at 3.3 V with a 15 pF load. Input capacitance is 3.5 pF, and power dissipation capacitance per gate is 24 pF. It is housed in a 14-pin SOIC package.

Inverter Gates Procurement Notes

Verify the manufacturer origin as the component was originally produced by Philips Semiconductors before the brand transition to NXP/Nexperia. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range aligns with the system environment requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Inverter Gates Selection Notes

Select this component for designs requiring triple 3-input NOR gates in a low-voltage CMOS process. It serves as a direct replacement for older 74HC/HCT27 devices where lower voltage operation is beneficial. Consider the propagation delay specifications relative to the system clock speed. Evaluate the power dissipation characteristics against the thermal constraints of the application.

Inverter Gates Part Context

This part belongs to the 74LV series of low-voltage CMOS logic integrated circuits. The series is designed to bridge the gap between traditional 5V logic and modern lower voltage systems. The 74LV27 specifically implements the NOR function, which is fundamental in digital logic design for creating complex switching networks and control signals.

Inverter Gates Replacement Considerations

The datasheet states the device is pin and function compatible with the 74HC27 and 74HCT27. Designers can substitute these parts directly without circuit modification, provided the voltage levels and timing requirements are met.
