ET74LVC1G07

Overview

The ET74LVC1G07 is a single buffer/driver with open-drain output from the ETEK MICROELECTRONICS LVC series. It operates within a supply voltage range of 1.65V to 5.5V, supporting mixed 3.3V and 5V system environments. The device features Schmitt trigger inputs for noise tolerance and includes IOFF circuitry for partial power-down applications. It provides an output drive current of ±24mA at VCC=3.0V and maintains low static power consumption. The component is designed for high-speed operation with typical propagation delays around 4ns at 3.3V.

Feature Summary

• Open-drain output configuration allows wired-AND or wired-OR logic implementation
• Schmitt trigger action on all inputs ensures tolerance for slow rise and fall times
• IOFF circuitry disables outputs during partial power-down to prevent backflow current
• Direct interface capability with TTL levels and input voltages up to 5V

Applications

• Mixed 3.3V and 5V system environments
• Partial power-down applications requiring backflow prevention
• Buffering signals with slow transition times

Procurement Notes

Verify the manufacturer designation as ETEK MICROELECTRONICS against official datasheets, as this part number primarily corresponds to Nexperia's 74LVC1G07 family. Confirm package type, pinout compatibility, and electrical specifications match your design requirements before procurement. Ensure the specific variant meets your voltage and temperature constraints.

Selection Notes

Select this component when a single-channel non-inverting buffer with open-drain output is required. It is suitable for level shifting between 3.3V and 5V domains due to its wide input voltage tolerance. Consider the IOFF feature if the design involves partial power-down states to protect downstream components from reverse current flow.

Part Context

This component belongs to the 74LVC1G07 logical buffer family, characterized by low-voltage CMOS technology. Similar devices include the Nexperia 74LVC1G07 and TI SN74LVC1G07, which share identical functional descriptions and electrical characteristics. These parts are widely used in portable electronics and industrial control systems requiring compact, low-power signal buffering solutions.

Replacement Considerations

Nexperia 74LVC1G07 and Texas Instruments SN74LVC1G07 are functionally equivalent replacements. Verify that the substitute part matches the required package footprint and lead time availability.
