SN74LVC1G17DCKR Single Schmitt-Trigger Buffer: Schematic, Pinout, and Datasheet

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

The SN74LVC1G17DCKR is a single-buffer device that performs the Boolean operation Y = A.

Over a wide Vcc operating range, the CMOS device has a high output drive while maintaining low static power dissipation.

The SN74LVC1G17DCKR comes in a variety of packages, including the ultra-compact DPW packaging, which has a body size of 0.8 mm.

The device works as a standalone buffer, but due to Schmitt action, it has differing input threshold values for positive (VT+) and negative (VT-) signals.

The DPW package technology is a significant advancement in IC packaging. Its compact 0.64 mm square footprint saves a lot of room on the board compared to other package options while keeping the typical 0.5 mm lead pitch.

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.

Functional Block Diagram

This device features a balanced output drive and is based on CMOS technology.

Typical Application

Bus congestion should be avoided at all costs because it can cause currents to exceed permissible limits. To avoid ringing, the high drive will cause quick edges into mild loads, hence routing and load circumstances should be considered.

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.
