The abbreviation for "Temperature Compensated Crystal Oscillator." Such an oscillator contains a temperature sensing network that adjusts the output frequency, thereby allowing the frequency to remain constant over a specified temperature range.
T.C.V.C.X.O
The abbreviation for "Temperature Compensated Voltage Control Crystal Oscillator." Such an oscillator contains a temperature and voltage sensing network that adjusts the output frequency, thereby allowing the frequency to remain constant over a specified temperature range.
TRI-STATE
The ability to turn the output on or off using pin one for control. The output will go to a high impedance when disabled, which facilitates the use of Auto Test Equipment (ATE). Note: Tri-state may be substituted for non-Tri-state if pin #1 is left open or held high.
TTL
The abbreviation for "Transistor-Transistor Logic".
