NC − No internal connection
The TLC274 and TLC279 quad operational
amplifiers combine a wide range of input offset
voltage grades with low offset voltage drift, high
input impedance, low noise, and speeds
approaching that of general-purpose BiFET
devices.

These devices use Texas Instruments silicon-
gate LinCMOS technology, which provides
offset voltage stability far exceeding the stability
available
with
conventional
metal-gate
processes.
The extremely high input impedance, low bias
currents, and high slew rates make these
cost-effective devices ideal for applications which
have previously been reserved for BiFET and
NFET products. Four offset voltage grades are
available (C-suffix and I-suffix types), ranging
from the low-cost TLC274 (10 mV) to the high-
precision TLC279 (900
µV).
These advantages, in
combination with good common-mode rejection
and supply voltage rejection, make these devices
a good choice for new state-of-the-art designs as
well as for upgrading existing designs.

description (continued)
In general, many features associated with bipolar technology are available on LinCMOS operational
amplifiers, without the power penalties of bipolar technology. General applications such as transducer
interfacing, analog calculations, amplifier blocks, active filters, and signal buffering are easily designed with the
TLC274 and TLC279. The devices also exhibit low voltage single-supply operation, making them ideally suited
for remote and inaccessible battery-powered applications. The common-mode input voltage range includes the
negative rail.
A wide range of packaging options is available, including small-outline and chip-carrier versions for high-density
system applications.
The device inputs and outputs are designed to withstand −100-mA surge currents without sustaining latch-up.
The TLC274 and TLC279 incorporate internal ESD-protection circuits that prevent functional failures at voltages
up to 2000 V as tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in handling
these devices as exposure to ESD may result in the degradation of the device parametric performance.
The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized
for operation from − 40°C to 85°C. The M-suffix devices are characterized for operation over the full military
temperature range of −55°C to 125°C.

TLC274Y chip information
These chips, when properly assembled, display characteristics similar to the TLC274C. Thermal compression
or ultrasonic bonding may be used on the doped-aluminum bonding pads. Chips may be mounted with
conductive epoxy or a gold-silicon preform.
