1. General description

The 74AUP1Z125 is a crystal driver with enable, internal resistor and 3-state output. 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 in the high impedance OFF-state. In disable mode the

output Y assumes the high impedance OFF-state. Schmitt trigger action on the EN input makes the

circuit tolerant to slower input rise and fall times across the entire VCC range from 0.8 V to 3.6 V.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
