The maximum operating temperature range for CY7C109-20VC is 0°C to 70°C (commercial grade) and -40°C to 85°C (industrial grade).
The CY7C109-20VC requires a clock signal to operate. You can use an external clock source or generate a clock signal using a crystal oscillator or a phase-locked loop (PLL) circuit.
The maximum clock frequency supported by CY7C109-20VC is 20 MHz.
During power-up, ensure that the clock signal is stable before applying VCC. During power-down, ensure that VCC is removed before removing the clock signal.
The recommended termination scheme for CY7C109-20VC is to use a 10-ohm resistor in series with a 10-pF capacitor to ground on each output pin.
