Low-power X-tal driver with enable and internal resistor
●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, putting the device in a low power disable mode with X1 pulled HIGH via RPU, X2 set LOW and Y set HIGH.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.
●Features and benefits:
■Wide supply voltage range from 2.3 V to 3.6 V
■High noise immunity
■ESD protection:
▲HBM JESD22-A114F Class 3A exceeds 5000 V
▲MM JESD22-A115-A exceeds 200 V
▲CDM JESD22-C101E exceeds 1000 V
■Latch-up performance exceeds 100 mA per JESD 78 Class II
■Inputs accept voltages up to 3.6 V
■Low noise overshoot and undershoot < 10 % of V-CC
■I-OFF circuitry provides partial Power-down mode operation at output Y
■Multiple package options
■Specified from -40 °C to +85 °C and -40 °C to +125 °C
