The MC10/100EL57 is a 4:1 multiplexer from Motorola. It can be used in 4:1 mode or 2:1 mode by switching the SEL1 line. In 4:1 mode, SEL0 selects between D0 and D1. In 2:1 mode, SEL0 selects between D0 and D1. The EL57 has a fully differential architecture, making it ideal for use in low skew applications such as clock distribution.
This document is a technical datasheet for the Motorola MC10EL57 and MC100EL57, which are fully differential 4:1 multiplexers. The device architecture allows it to function as a 2:1 multiplexer by leaving the SEL1 line open, making it suitable for low skew applications such as clock distribution. It features multiple VBB outputs for single-ended or AC coupled interfaces and includes 75kΩ internal input pulldown resistors.

Yes, by leaving the SEL1 line open, the device can function as a differential 2:1 multiplexer.
SEL1 is the most significant select line used to choose between the four data inputs.
The output can source or sink up to 50 mA continuously.
