ELANTEC EL5123C

12MHz 4-, 8-, 10- & 12-Channel Rail-to-Rail Input-Output Buffers
Features
General Description
• 12MHz -3dB bandwidth
• Supply voltage = 4.5V to 16.5V
• Low supply current (per buffer) =
600µA
• High slew rate = 15V/µs
• Rail-to-rail input/output swing
• Ultra-small packages
The EL5123C, EL5223C, EL5323C, and EL5423C are low power,
high voltage rail-to-rail input/output buffers designed primarily for use
in reference voltage buffering applications for TFT_LCDs. They are
available in quad (EL5123C), octal (EL5223C), 10-channel
(EL5323C), and 12-channel (EL5423C) topologies. All buffers feature
a -3dB bandwidth of 12MHz and operate from just 600µA per buffer.
This family also features fast slewing and settling times, as well as a
continuous output drive capability of 30mA (sink and source).
