The Fairchild Semiconductor 100EL16MX is a high-speed differential receiver belonging to the ECL (Emitter-Coupled Logic) family. Designed for 3.3V operation, this component functions as a single-channel receiver that converts differential ECL signals into compatible logic levels. It utilizes a surface-mount package configuration suitable for dense circuit board layouts. The device supports standard ECL voltage swings and timing characteristics required for high-frequency digital signal processing applications.
Verify the manufacturer origin carefully, as Fairchild Semiconductor's logic division was acquired by ON Semiconductor. Ensure the specific suffix matches the required tape-and-reel or tube packaging format. Confirm RoHS compliance status if environmental regulations apply to the target assembly process.
Select this component when a single differential receiver channel is required within a 3.3V ECL environment. Compare pinout compatibility with existing PCB footprints against modern equivalents from ON Semiconductor. Verify that the operating temperature range meets the specific system thermal requirements.
This part belongs to the legacy Fairchild ECL product line, which has been integrated into ON Semiconductor’s portfolio. The '100' prefix typically denotes the standard ECL series, while 'L' indicates low-power variants. This specific model represents a discontinued or legacy item often replaced by updated series parts.
ON Semiconductor MC100LVEL16 is a direct functional equivalent. Check for suffix variations indicating package type or lead-free composition. Verify electrical parameter alignment before substitution.
