Part Number	MC10EL57 Datasheet
Manufacturer	onsemi
Overview	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. * Useful as Either 4:1 or 2:1 Multiplexer * VBB Output for Single-Ended Operation * PECL Mode Operating Range: VCC = 4.2 V to 5.7 V with VEE = 0 V * NECL Mode Operating Range: VCC = 0 V with VEE = *4.2 V to *5.7 V * Internal Input Pulldown Resistors on All Inputs * Q Outputs Will Default LOW with In.
