SN74HCS05QPWRQ1

Inverter Gates Overview

The SN74HCS05QPWRQ1 is an automotive-grade hex inverter featuring open-drain outputs and Schmitt-trigger inputs. It operates within a supply voltage range of 2 V to 6 V and supports an ambient temperature range from -40°C to +125°C. The device provides ±7.8 mA output drive capability at 5 V. Propagation delay ranges from 12 ns to 39 ns depending on voltage. Input leakage current is typically ±100 nA, with typical supply current of 100 nA.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide noise rejection for slow or noisy signals
• Open-drain CMOS outputs allow for level-shifting and wired-AND configurations
• Low power consumption with minimal static current draw
• AEC-Q100 qualified for automotive reliability standards

Inverter Gates Applications

• Drive indicator LEDs
• Level-shift using open-drain outputs
• Invert a digital signal

Inverter Gates Procurement Notes

Verify the specific package variant (TSSOP vs SOIC) matches the design footprint. Confirm AEC-Q100 qualification requirements align with target automotive grade. Ensure input termination strategies are defined for unused channels to prevent floating states. Validate thermal dissipation calculations against absolute maximum ratings during operation.

Inverter Gates Selection Notes

Select this component when open-drain logic inversion is required in automotive environments. The Schmitt-trigger inputs make it suitable for noisy signal lines where standard CMOS might oscillate. Verify that the external pull-up resistor values accommodate the desired voltage levels and switching speeds. Consider the propagation delay limits for high-speed timing applications.

Inverter Gates Part Context

This part belongs to the Texas Instruments SN74HCS05-Q1 family of single-function gates. It is specifically designed for automotive applications requiring robust noise immunity and wide voltage operation. The HCS series combines CMOS low power with Schmitt-trigger functionality.

Inverter Gates Replacement Considerations

SN74HCS05QDRQ1 offers the same electrical characteristics in a SOIC-14 package instead of TSSOP-14.
