Applications — Applications that are described herein for any of these products are for illustrative purposes only. HC, or look datazheet some with schmitt-trigger. But I wouldn’t rely on “typical” values if you want a robust design. Ordering information Table 1. A short data sheet is intended for quick reference only and should not be relied upon to contain detailed and full information.
74hct424d A digital pin can drive 40mA, up to a total of mA. Contact information For more information, please visit: So a 74 HCT xatasheet indeed the proper 74hct244d. Please, contact us at support mbed. In my opinion the 74HCT “trick” isn’t really a trick, the voltage levels are right because the parts are designed that way. I have used the 74HC as logic converter, which worked flawlessly. Revision history Table If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.
Limiting values are stress ratings only and proper operation of the device at these or any other conditions above those given in the Recommended operating conditions section if present or the Characteristics sections of this document is not warranted.
The English version shall prevail in case of any discrepancy between the translated and English versions. Normally for input I connect direct or with a resistor divider. Constant or repeated exposure to limiting values will permanently and irreversibly affect the quality and reliability of the device.

You can look at the data sheets how the logic high voltage is defined should be either 2 volts, 0. As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: For more information, please visit: Static characteristics Table 6. And it’s available in an easy-to-use through-hole package. For output direct connection without problems. Find answers to your design questions on this page. Then you could buffer the signal up.
