SN74AHC05PW

Overview

The SN74AHC05PW is a hex inverter with open-drain outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature from -40°C to +85°C. The device features latch-up performance exceeding 250 mA per JESD 17 and ESD protection ratings of 2000 V (HBM), 200 V (MM), and 1000 V (CDM). Propagation delay ranges from 1 ns to 12 ns depending on load capacitance and voltage.

Feature Summary

• Contains six independent inverters performing the Boolean function Y = A.

Applications

• Implementing active-low wired-OR functions
• Implementing active-high wired-AND functions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation, as availability status may vary between tube and tape-and-reel packaging formats. Confirm that the selected package variant matches the required thermal impedance and moisture sensitivity level for the intended assembly process.

Selection Notes

Select this component when a hex inverter with open-drain output capability is required for mixed-voltage interfacing or bus line applications. Ensure external pull-up resistors are included in the design, as the open-drain architecture requires them to establish high logic states correctly.

Part Context
