BUF04701
SBOS214B SEPTEMBER 2001 REVISED JULY 2004
DESCRIPTION
The BUF04701 is a 4-channel, low-power, high-voltage rail-
to-rail input/output buffer. Operating on supplies ranging from
3.5V to 12V (
1.75V to
6V), the BUF04701 has a 3dB
bandwidth of 8MHz with a slew rate of 10V/
s, and requires
only 1.1mA quiescent current. The BUF04701 features rail-
to-rail input and output capability, giving maximum dynamic
range at any supply voltage.
Featuring fast slewing and settling times, as well as a high
output drive, the BUF04701 is ideal for use as a voltage
reference buffer in Thin Film Transistor Liquid Crystal Dis-
plays (TFT-LCDs).
The BUF04701 is available in an MSOP-10 package, provid-
ing the smallest footprint and thinnest package option avail-
able, as well as the TSSOP-14 package with a pinout that
corresponds to standard quad op amps. This makes it easy to
replace quad op amps in existing LCD displays with the low
cost BUF04701, without changing the layout. The BUF04701
operates over a temperature range of 40
C to +125
C.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may
degrade device reliability. (2) Input terminals are diode-clamped to the
power-supply rails. Input signals that can swing more than 0.5V beyond the
supply rails should be current-limited to 10mA or less. (3) Short-circuit to
ground, one amplifier per package.
ABSOLUTE MAXIMUM RATINGS

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
