The EL5127, EL5227, EL5327, and EL5427 are low power,
Features
high voltage rail-to-rail input/output buffers designed for use
in reference voltage buffering applications in small LCD
displays. They are available in quad (EL5127), octal
(EL5227), 10-Channel (EL5327), and 12-Channel (EL5427)
topologies. All buffers feature a -3dB bandwidth of 2.5MHz
and operate from just 133µA per buffer. This family also
features a continuous output drive capability of 30mA (sink
and source).
• 2.5MHz -3dB bandwidth
DATASHEET
FN7111
Rev 4.00
May 4, 2007
• Supply voltage = 4.5V to 16.5V
• Low supply current (per buffer) = 133µA
• High slew rate = 2.2V/µs
• Rail-to-rail input/output swing
• Ultra-small packages
• Pb-free plus anneal available (RoHS compliant)
The quad channel EL5127 is available in the 10 Ld MSOP
package. The 8-Channel EL5227 is available in both the
20 Ld TSSOP and 24 Ld QFN packages, the 10-Channel
EL5327 in the 24 Ld TSSOP and 24 Ld QFN packages, and
the 12-Channel EL5427 in the 28 Ld TSSOP and 32 Ld QFN
packages. All buffers are specified for operation over the full
-40°C to +85°C temperature range.
Applications
• TFT-LCD drive circuits
• Electronic games
• Touch-screen displays
• Personal communication devices
• Personal digital assistants (PDAs)
• Portable instrumentation

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
