The maximum frequency of operation for the 74HC123D is typically around 20-30 MHz, but this can vary depending on the specific application and operating conditions.
To ensure proper power and decoupling, connect the VCC pin to a stable 5V power supply, and decouple the power supply lines with 0.1uF ceramic capacitors as close to the device as possible. Additionally, use a 10uF electrolytic capacitor for bulk decoupling.
The recommended operating temperature range for the 74HC123D is -40°C to +125°C, but it can operate up to 150°C for short periods of time.
The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure proper operation. A low signal on MR will reset the device.
The propagation delay time for the 74HC123D is typically around 10-20 ns, but this can vary depending on the specific application and operating conditions.
