SN74AC05PWRQ1

Overview

The SN74AC05PWRQ1 is an automotive-grade hex inverter with open-drain outputs from the SN74AC05-Q1 family. It operates within a supply voltage range of 1.5V to 6V and supports an operating temperature range of -40°C to +125°C. The device provides continuous output drive currents up to 24mA at 5V, with short-burst capability reaching 75mA. It features a maximum propagation delay of 6.6ns at 5V with a 50pF load and includes AEC-Q100 qualification for automotive reliability.

Feature Summary

• AEC-Q100 qualified for automotive applications with specified temperature grades and ESD classifications
• Wide operating voltage range supporting 1.5V to 6V supply levels
• Open-drain CMOS outputs capable of driving 50Ω transmission lines

Applications

• Drive indicator LEDs
• Synchronize inverted clock inputs
• Invert digital signals

Procurement Notes

Verify the specific package variant (TSSOP-14) against project requirements. Confirm that the open-drain output architecture aligns with the system's pull-up resistor strategy. Ensure input transition rates meet recommended conditions to prevent oscillation. Validate thermal management for the TSSOP package under expected load conditions.

Selection Notes

Select this component when automotive qualification is mandatory and wide voltage compatibility is required. The open-drain configuration is suitable for wired-AND logic or level shifting. Consider the 24mA continuous drive capability for direct LED interfacing. Evaluate the 6.6ns propagation delay against system timing constraints.

Part Context

This part belongs to the SN74AC05-Q1 series of hex inverters designed for automotive environments. It complements other AC-series logic devices by providing robust signal inversion with high drive strength. The inclusion of wettable flank options in the broader family aids in automated optical inspection reliability.
