Overview
The MC100EL57DR2G is a fully differential 4:1 multiplexer from the onsemi MC100E logic series, housed in a 16-pin SOIC package. It operates within a power supply range of -4.2 V to -5.7 V for VEE (with VCC at 0 V) or 4.2 V to 5.7 V for VCC (with VEE at 0 V). The device features an internal input pulldown resistor of 75 kΩ and provides two VBB reference voltage outputs. Propagation delay ranges from 350 ps to 580 ps depending on the signal path and temperature conditions.
Feature Summary
- Configurable as either a 4:1 or 2:1 multiplexer by leaving the SEL1 line open.
- Includes internally generated VBB outputs to support single-ended or AC coupled interfaces.
- All inputs are equipped with internal pulldown resistors to ensure stable default states.
- Outputs default to LOW when inputs are left open or held at VEE.
Applications
- SONET/SDH clock and data multiplexing
- Fibre Channel and Gigabit Ethernet signal distribution
- Multiplex and fanout applications for storage peripherals
Procurement Notes
Verify component authenticity through authorized channels. Confirm RoHS compliance and Pb-free status. Check for discontinuation notices as the device may be obsolete. Ensure proper handling for ESD-sensitive components during installation.
Selection Notes
Select this part for high-speed differential signal routing requiring low skew. Consider the 100 series temperature compensation if operating across wide thermal ranges. Verify interface compatibility with PECL or NECL standards before integration.
Part Context
This component belongs to the MC100EL57 family of ECL multiplexers. It shares functional similarities with the MC10EL57 but includes specific temperature compensation characteristics inherent to the 100 series designation.
Replacement Considerations
MC100EL57DG is listed as a discontinued alternative. Contact manufacturer representatives for current replacement options.
FAQ
How does the device function as a 2:1 multiplexer?
By leaving the SEL1 line open, which pulls it LOW via internal resistors, the device selects between D0 and D1 based solely on the SEL0 input.
What is the purpose of the VBB pins?
VBB provides an internally generated reference voltage used for single-ended input conditions or to rebias AC coupled inputs.
