12MHz Rail-to-Rail Input-Output Buffer
The EL5421T is a high voltage rail-to-rail input-output buffer
with low power consumption. The EL5421T contains four
buffers. Each buffer exhibits beyond the rail input capability,
rail-to-rail output capability and is unity gain stable.
The maximum operating voltage range is from 4.5V to 19V. It
can be configured for single or dual supply operation, and
typically consumes only 500µA per buffer. The EL5421T has
an output short circuit capability of ±200mA and a
continuous output current capability of ±70mA.
The EL5421T features a slew rate of 12V/µs. Also, the
device provides common mode input capability beyond the
supply rails, rail-to-rail output capability, and a bandwidth of
12MHz (-3dB). This enables the buffers to offer maximum
dynamic range at any supply voltage. These features make
the EL5421T an ideal buffer solution for use in TFT-LCD
panels as a VCOM or static gamma buffer, and in high speed
filtering and signal conditioning applications. Other
applications include battery power and portable devices,
especially where low power consumption is important.
The EL5421T is available in a space saving 10 Ld MSOP
package and operates over an ambient temperature range
of -40°C to +85°C.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is 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.

NOTES:
2. Measured over -40°C to +85°C ambient operating temperature range. See the typical TCVOS production distribution shown in the
“Typical Performance Curves” on page 5
3. Typical slew rate is an average of the slew rates measured on the rising (20% to 80%) and the falling (80% to 20%) edges of the output signal.
4. Settling time measured as the time from when the output level crosses the final value on rising/falling edge to when the output level settles within
a ±0.1% error band. The range of the error band is determined by: Final Value(V)±[Full Scale(V)*0.1%]
