Overview
The SN74LVC1G97DCKR, produced by Texas Instruments, is a configurable multiple-function gate that offers a high degree of flexibility in digital logic applications. This device is part of the LVC (Low-Voltage CMOS) family and is designed to operate over a wide voltage range of 1.65 V to 5.5 V, making it suitable for various system designs. The SN74LVC1G97DCKR is available in a 6-pin SC-70 package and is known for its low power consumption and high output drive capability.
This component has been discontinued by Texas Instruments, but it remains relevant for existing designs and legacy systems. It features CMOS technology, which provides balanced output drive and supports partial-power-down applications with Ioff circuitry to prevent backflow currents.
