SN74LVC1G17QDCKRQ1 Schmitt-Trigger Buffer: Diagram, Pinout, and Datasheet

This single Schmitt-trigger buffer is meant to operate between 1.65 and 5.5 V VCC.

The SN74LVC1G17QDCKRQ1 has one buffer and performs the Y = A Boolean function.

Over a wide VCC working range, the CMOS device has a high output drive while keeping low static power dissipation.

The SN74LVC1G17QDCKRQ1 comes in a number of different packages.

The following figure is SN74LVC1G17QDCKRQ1 Pinout.

The following is SN74LVC1G17QDCKRQ1 Simplified Schematic.

Simplified Schematic

This gadget features balanced output drive and CMOS technology. Bus congestion should be avoided at all costs, as it can cause currents to exceed the maximum allowable. To avoid ringing, the high drive will cause quick edges into light loads, hence routing and load circumstances must be considered.

Typical Application

Inputs should never float when using multiple-bit logic devices. When just two inputs of a triple-input  AND gate are used, or only three of the four buffer gates are used, many functions or parts of the functions of digital logic devices are unused. The undefined voltages at the outside connections result in undefined operating states, hence such input terminals should not be left disconnected. The rules that must be followed in all instances are listed below. 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 convenient.
