CD74HCT21MT Frequently Asked Questions (FAQ)
-
The recommended operating voltage range for the CD74HCT21MT is 4.5V to 5.5V, although it can operate down to 3.5V with reduced performance.
-
To ensure proper power-on and power-off, the VCC pin should be ramped up and down slowly (typically within 1ms) to prevent voltage spikes and noise. Additionally, the input signals should be stable and within the recommended voltage range before applying power.
-
The maximum frequency of operation for the CD74HCT21MT is typically around 30MHz, although this can vary depending on the specific application and operating conditions.
-
Unused inputs on the CD74HCT21MT should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and reduce power consumption. Floating inputs can cause the device to malfunction or consume excessive power.
-
The maximum output current that the CD74HCT21MT can sink or source is typically around 6mA, although this can vary depending on the specific application and operating conditions.
