Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is limited to devices with matching key parameters: category (Logic), logic type (Buffer, Non-Inverting), number of elements (2), number of bits per element (10), output type (3-State), output current (24mA high/low), supply voltage range (1.65V ~ 3.6V), surface mount configuration, identical package/case (56-BSSOP, 56-SSOP), RoHS and REACH compliance, and comparable MSL. Substitution is further restricted by the requirement for the same or wider operating temperature range and active or supported product status.

Parameter Comparison
