SN74HC266D is an integrated circuit that belongs to the Logic - Gates and Inverters family. It is a high performance 8-bit inverting buffer with Schmitt-trigger inputs. It was designed mainly for general purpose data buffering, clock drivers, and event counters applications.

The device has eight parallel inputs along with eight complemented outputs. The Schmitt-trigger inputs eliminate the need for external pull-up resistors and provide full logic level conversions. The Schmitt-trigger design helps ensure that logic levels at the outputs will not be affected by noise signals present at the inputs.

SN74HC266D has an internally wired Schmitt network that is able to translate input signal from TTL levels (0 - 3.3V) to CMOS levels (0 - 5V). All eight outputs are complementary and they produce a signal that is opposite of their input. One of the applications of this device is driving the data to the address pins of buses that are operated over five volts current.

SN74HC266D is a very versatile IC since it can be used in a wide range of applications like driving common-emitter and emitter-coupled logic (ECL) gates, driving four-bit adders and controllers, buffering clock and address signals, as well as in wide range of output stages. It can be used in different types of logic gates such as AND, OR, and NOT.

The working principle of SN74HC266D is quite simple. The device has a set of eight Schmitt-trigger inputs and eight output buffer stages that are connected in series. When the input signal is applied, the Schmitt-trigger buffers convert the TTL level signal to CMOS level signal and it is further amplified to the output stage. The output stage then produces a signal that is opposite of the input.

When it comes to the power requirements, SN74HC266D is able to operate with a wide range of power supply voltages ranging from 2.7V to 6V with a maximum quiescent supply current of 1.6mA. The device is specified to operate over a range of temperatures ranging from -40°C to 125°C, making it suitable for use in a wide range of climates as well.

In summary, SN74HC266D is a versatile logic-gates and inverters IC that is suitable for a range of applications such as clock drivers, event counters, and data buffering. Its Schmitt design helps ensure that logic levels at the outputs will not be affected by noise signals present at the inputs. It has an internally wired Schmitt network that can translate input signal from TTL levels (0 - 3.3V) to CMOS levels (0 - 5V). In addition, the device has a wide range of power supply voltage (2.7V - 6V) and a specified temperature range (-40°C to 125°C) making it suitable for use in a wide range of climates.
