The recommended operating voltage range for the HEF4555BP is 3V to 15V, although it can operate down to 2V with reduced performance.
To ensure proper power-on and power-off, it's recommended to use a slow-rising power supply voltage (typically 1-10 ms) and to avoid voltage spikes or dips during power-on and power-off transitions.
The maximum clock frequency that the HEF4555BP can handle is 100 kHz, although it can operate at higher frequencies with reduced performance and increased power consumption.
To minimize power consumption, use a low-power oscillator, reduce the clock frequency, and use a low-voltage power supply. Additionally, consider using the device's power-down mode when not in use.
To minimize noise and ensure proper operation, it's recommended to use a symmetrical layout, keep the clock signal away from the power supply lines, and use a ground plane to reduce electromagnetic interference (EMI).
