Low-power X-tal driver with enable and internal resistor
Rev. 02 — 3 July 2008
Product data sheet
1. General description
The 74AUP1Z04 combines the functions of the 74AUP1GU04 and 74AUP1G04 with
enable circuitry and an internal bias resistor to provide a device optimized for use in
crystal oscillator applications.
When not in use the EN input can be driven HIGH, pulling up the X1 input and putting the
device in a low power disable mode. Schmitt trigger action at the EN input makes the
circuit tolerant to slower input rise and fall times across the entire V_CC range from 0.8 V to
3.6 V.
This device is fully specified for partial power-down applications using I_OFF at output Y.
The I_OFF circuitry disables the output Y, preventing the damaging backflow current through
the device when it is powered down.
The integration of the two devices into the 74AUP1Z04 produces the benefits of a
compact footprint, lower power dissipation and stable operation over a wide range of
frequency and temperature.
