SN74LVC2G17DCKR Dual Schmitt-Trigger Buffer: Circuit, Pinout, and Datasheet

This Dual Schmitt-Trigger Buffer is rated for a VCC range of 1.65 to 5.5 volts.

The SN74LVC2G17DCKR is a two-buffer device that performs the Y = A Boolean function. The device acts as two separate buffers, but due to Schmitt action, the input threshold levels for positive (VT+) and negative (VT–) signals may differ.

The NanoFreeTM package technology, which uses the die as the package, is a major development in IC packaging technologies.

This device is completely qualified for Ioff-based partial-power-down applications. When the device is turned off, the Ioff circuitry disables the outputs, preventing dangerous current backflow through the device.

The following shows SN74LVC2G17DCKR Pinout.

Positive Logic

Device Power Button Circuit

This device features a balanced output drive and is based on CMOS technology. Bus congestion should be avoided at all costs because it can cause currents to exceed permissible limits. The higher drive can be achieved by combining outputs, but this will result in faster edges into mild loads, therefore routing and load circumstances should be examined to avoid ringing.

Inputs should not float when using multiple bit logic devices. Functionalities or parts of functions of digital logic devices are frequently left unused. When only two inputs of a triple-input AND gate are used, or when only three of the four buffer gates are used, these are examples. The undefined voltages at the outside connections result in undefined operating states, hence such input pins should not be left disconnected.

The following diagram illustrates the principles that must be followed at all times. To prevent floating, all unused inputs of digital logic devices must be connected to a high or low bias. The logic level that should be applied to any given unused input is determined by the device's function. They'll usually be connected to GND or VCC, depending on which makes more sense or is more handy.
