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 TLC272 and
TLC277. 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 TLC272 and TLC277 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.

TLC272Y chip information
This chip, when properly assembled, displays characteristics similar to the TLC272C. 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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to network ground.
2. Differential voltages are at IN+ with respect to IN–.
3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded (see application section).
