'T' (Tri-state), when pin 1 is LOW, the oscillator continues to run, hoever, the output buffer amplifier stops functioning and output is in a high impedance (Z) state. -10° to +70°C -40° to +85°C -55° to +125°C ENABLE vs TRI-STATE Current consumption when Pin 1 is low Output recovery delay when Pin 1 changes from low to high ABSOLUTE MAXIMUM RATINGS Supply Voltage: Storage Temperature: Enable Tri-State Low High Delayed Immediate -0.3V to +7.0V -55° to +125°C PACKAGING LXOM-AT oscillators are supplied tube packed.
