General Description

The EL2170CEL2270CEL2470C are singledualquad cur-

1 mA of supply current per amplifier They will operate with

current the EL2270C and the EL2470C can output 55 mA while

100 mA with similar output swings These attributes make the

EL2170CEL2270CEL2470C excellent choices for low power

andor low voltage cable-driver HDSL or RGB applications

For applications where board space is extremely critical the

EL2170C is available in the tiny 5-Lead SOT23 package which

has a footprint 28% the size of an 8-Lead SOIC The EL2170C

EL2270CEL2470C are each also available in industry standard

pinouts in PDIP and SOIC packages

For Single and Dual applications with disable consider the

EL2176C (8-Pin Single) or EL2276C (14-Pin Dual) For higher

speed applications where power is still a concern consider the

EL2180CEl2186C family which also comes in similar Single

Dual Triple and Quad configurations The EL2180CEL2186C

ing 3 mA of supply current per amplifier
