SN74HCS11QPWRQ1

Inverter Gates Overview

The SN74HCS11QPWRQ1 is a Texas Instruments automotive-grade AND gate IC featuring three independent 3-input channels. It utilizes High-Speed CMOS (HCS) technology with Schmitt-trigger inputs for noise immunity. The device operates within a supply voltage range of 2V to 6V, supporting logic levels from 1V to 3V (low) and 1.5V to 4.2V (high). It offers output currents of 7.8mA for both high and low states, with a maximum static current of 2µA. Propagation delay is specified at 16ns @ 6V, 50pF. Packaged in a 14-TSSOP surface-mount case, it functions between -40°C and 125°C and holds AEC-Q100 qualification.

Inverter Gates Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package type and tape/reel specifications. Confirm AEC-Q100 certification status is required for your specific automotive application tier. Check for any recent Product Change Notifications regarding assembly sites or material composition updates before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when designing automotive digital logic circuits that require precise timing and noise tolerance. The HCS series provides a balance of speed and power efficiency suitable for battery-operated vehicle systems. Ensure input voltage levels align with the specified 1V-3V low and 1.5V-4.2V high ranges for reliable operation across the full industrial temperature spectrum.

Inverter Gates Part Context

This device belongs to the SN74HCS family of high-speed CMOS logic gates. The 'Q1' suffix denotes its qualification for automotive applications, distinguishing it from standard commercial variants. It shares the functional core of the SN74HCS11 but includes specific packaging and testing protocols mandated by automotive industry standards for long-term durability and consistency.

Inverter Gates Replacement Considerations

Direct replacements must maintain AEC-Q100 qualification and identical pinout. Verify that substitute parts support the same 3-channel 3-input AND configuration and Schmitt-trigger input characteristics. Ensure the alternative component meets the 2V-6V supply voltage range and 14-TSSOP package dimensions.
