The MC10/100EL57 is a fully differential 4:1 multiplexer. By leaving the SEL1 line open (pulled LOW via the input pulldown resistors) the device can also be used as a differential 2:1 multiplexer with SEL0 input selecting between D0 and D1. The fully differential architecture of the EL57 makes it ideal for use in low skew applications such as clock distribution.

• Useful as Either 4:1 or 2:1 Multiplexer
• VBB Output for Single-Ended Operation
• 75kΩ Internal Input Pulldown Resistors
• >1000V ESD Protection
