The CD74HC299M can handle clock frequencies up to 25 MHz.
The CD74HC299M requires a single power supply voltage (VCC) of 2.0 V to 6.0 V, and it is recommended to decouple the power supply with a 0.1 μF capacitor.
The CD74HC299M can tolerate input voltages up to 7.0 V, but it is recommended to keep input voltages within the power supply voltage (VCC) range.
The CD74HC299M has an active-low reset input (MR) that can be used to reset the device. A low signal on the MR input will reset the device.
The propagation delay of the CD74HC299M is typically around 10 ns to 20 ns, depending on the operating frequency and voltage.
