SN74LS266N

Inverter Gates Overview

The SN74LS266N is a quadruple 2-input exclusive-NOR gate featuring open-collector outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 30 ns at a load capacitance of 50 pF. The device provides a low-level output current of 8 mA and functions reliably across an operating temperature range of 0°C to 70°C. It utilizes a standard 14-pin dual in-line package (PDIP) for through-hole mounting.

Inverter Gates Procurement Notes

Verify that the specific orderable part number matches the required package type and lead finish. Confirm RoHS compliance status as indicated in the packaging information addendum. Ensure the selected variant aligns with the intended operating temperature range and application requirements before finalizing procurement.

Inverter Gates Selection Notes

Select this component when a quadruple 2-input exclusive-NOR function with open-collector outputs is required. The LS series offers standard switching speeds compatible with general-purpose applications. Verify that the system design accommodates the open-collector nature of the outputs, which necessitates external pull-up resistors for proper high-state operation.

Inverter Gates Part Context
