CD74HC640E Frequently Asked Questions (FAQ)
-
The maximum frequency of operation for the CD74HC640E is 25 MHz, but it can vary depending on the specific application and operating conditions.
-
It is recommended to power up the VCC pin before the VEE pin, and power down the VEE pin before the VCC pin to prevent latch-up and ensure proper operation.
-
The recommended operating voltage range for the CD74HC640E is 2V to 6V, with a typical operating voltage of 5V.
-
It is recommended to use a termination resistor (e.g. 33 ohms) at the end of the transmission line to prevent signal reflections and ensure proper signal integrity.
-
Yes, the CD74HC640E can operate at 3.3V, but the output voltage swing will be reduced, and the device may not meet the specified propagation delay and transition time.
