SN74HCS266PWR

Inverter Gates Overview

The SN74HCS266PWR is a quadruple 2-input XNOR gate featuring open-drain outputs and Schmitt-trigger inputs. It operates within a supply voltage range of 2V to 6V, supporting an ambient temperature range from -40°C to +125°C. The device provides ±7.8mA output drive capability at 6V. Propagation delay ranges from 5ns to 40ns depending on voltage. Input leakage current is typically ±100nA, with typical supply current at 2µA.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for noise rejection and tolerance to slow input signals
• Open-drain CMOS outputs allow wired-AND configurations without bus contention
• Low power consumption with minimal static supply current

Inverter Gates Applications

• Detecting phase differences in input signals
• Creating selectable inverters or buffers
• Controlling clock source polarity

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-14 package variant. Confirm RoHS compliance and lead finish details via the manufacturer's orderable addendum. Ensure design requirements match the recommended operating conditions for voltage and thermal limits before procurement.

Inverter Gates Selection Notes

Select this component when open-drain logic compatibility or wired-AND functionality is required. The Schmitt-trigger inputs are suitable for noisy environments or signals with slow transition rates. Verify that the external pull-up resistor values align with the desired high-state voltage levels and capacitive load constraints.

Inverter Gates Part Context

This part belongs to the Texas Instruments HCS logic family, designed for low-power applications. It serves as a digital logic gate alternative to standard CMOS devices, offering enhanced noise immunity through its specific input architecture while maintaining compatibility with standard logic interfaces.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating. They should be terminated to either VCC or ground using a pullup or pulldown resistor, typically 10kΩ, to prevent undefined operational states.

Can multiple outputs be connected together?

Yes, the open-drain outputs can be directly connected to form a wired-AND configuration because they cannot source current, preventing bus contention.
