9.1 Overview

The SN74LVC1404 device consists of one inverter with a Schmitt-trigger input and two unbuffered inverters. It is designed for 1.65-V to 5.5-V VCC operation.

XIN and XOUT pins can be connected to a crystal or resonator in oscillator applications. The SN74LVC1404 device provides an additional unbuffered inverter (OSCOUT) and a Schmitt-trigger input inverter for signal conditioning (see the Functional Block Diagram). The control (CTRL) input disables the oscillator circuit to reduce power consumption. The oscillator circuit is disabled and the XOUT output is set to low level when CTRL is low. To ensure the oscillator circuit remains disabled during power up or power down, CTRL should be connected to GND through a pulldown resistor. The minimum value of the resistor is determined by the current-sourcing capability of the driver.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.
