FN7176.1
12MHz 4, 8, 10 & 12 Channel Rail-to-Rail
Input-Output Buffers
Features
• 12MHz -3dB bandwidth
The EL5123, EL5223, EL5323, and EL5423 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 (EL5123), octal
(EL5223), 10-channel (EL5323), and 12-channel (EL5423)
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).
• 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
• Pb-free available (RoHS compliant)
Applications
The quad channel EL5123 is available in the 10-pin MSOP
package. The 8-channel EL5223 is available in both the 20-
pin TSSOP and 24-pin QFN packages, the 10-channel
EL5323 in the 24-pin TSSOP and 24-pin QFN packages,
and the 12-channel EL5423 in the 28-pin TSSOP and 32-pin
QFN packages. All buffers are specified for operation over
the full -40°C to +85°C temperature range.
