The maximum clock frequency of the SN74LS85D is 10 MHz, but it can vary depending on the specific application and operating conditions.
To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF decoupling capacitor between VCC and GND, and use a 10uF capacitor between VCC and GND for additional filtering.
The maximum input voltage that the SN74LS85D can tolerate is 5.5V, exceeding which can cause damage to the device.
The CLR input should be tied to VCC through a 1kΩ resistor and a 0.01uF capacitor to ensure proper reset operation.
The propagation delay of the SN74LS85D is typically around 10-15 ns, but it can vary depending on the specific application and operating conditions.
