EL5421
FN7198.2
Quad 12MHz Rail-to-Rail Input-Output
Buffer
The EL5421 is a quad, low power, high voltage rail-to-rail
input-output buffer. Operating on supplies ranging from 5V to
15V, while consuming only 500µA per channel, the EL5421
has a bandwidth of 12MHz (-3dB). The EL5421 also
provides rail-to-rail input and output ability, giving the
maximum dynamic range at any supply voltage.
The EL5421 also features fast slewing and settling times, as
well as a high output drive capability of 30mA (sink and
source). These features make the EL5421 ideal for use as
voltage reference buffers in Thin Film Transistor Liquid
Crystal Displays (TFT-LCD). Other applications include
battery power, portable devices and anywhere low power
consumption is important.
The EL5421 is available in a space saving 10 Ld MSOP
package and operates over a temperature range of -40°C to
+85°C.
Features
• 12MHz -3dB bandwidth
• Unity gain buffer
• Supply voltage = 4.5V to 16.5V
• Low supply current (per buffer) = 500µA
• High slew rate = 10V/µs
• Rail-to-rail operation
• “Mini” SO package (MSOP)
• Pb-free plus anneal available (RoHS compliant)
Applications
• TFT-LCD drive circuits
• Electronics notebooks
• Electronics games
• Personal communication devices

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.
