Table 7 on page 45 gives the following limits for standard port pins: I haven’t seen any logic level converter in DIP packages.
Then you could buffer the signal up. Accept and hide this message. And it’s available in an easy-to-use through-hole package.

You do not have the correct permissions to perform this operation. Customers are responsible for the design and operation of their applications and products using NXP Semiconductors products, and NXP Semiconductors accepts no liability for any assistance with applications or customer product 74hct2444d.
I’d prefer a chip with lines, not necessarily bidirectional.
Please, contact us at support mbed. As most of my peripheral circuits run on 5V, 74hc2t44d need some way datashedt level shifting. All information provided in this document is subject to legal disclaimers. These are also nice level converters and in DIP package available too: The latest product status information is available on the Internet at URL http: However, NXP Semiconductors does not give any representations or warranties, expressed or implied, as to the accuracy or completeness of such information and shall have no liability for the consequences of use of such information.
Static characteristics Table 6.
The LPC data sheet explains this in more detail. In case of any inconsistency or conflict with the short data sheet, the full data sheet shall prevail. I have used the 74HC as logic converter, which worked flawlessly. Product specification — The information and data provided in a Product data sheet shall define the specification of the product as agreed between NXP Semiconductors and its customer, unless NXP Semiconductors and customer have explicitly agreed otherwise in writing.

Product [short] data sheet Production This document contains the product specification. Support Find answers to your design questions on this page. See Table 7 on page 6 of this data sheetunder “V IH “. There is one dirty trick that many of us use.
You might choose the 74HCT — that would give you 8 lines in a single package. Non-automotive qualified products — Unless this data sheet expressly states datasehet this specific NXP Semiconductors product is automotive qualified, the product is not suitable for automotive use.
Going to try some simple pullup resistors. In my opinion the 74HCT “trick” isn’t really a trick, the voltage levels are right because the parts are designed that way.

If your external devices are of 74HC or 74LS series, you can connect them safely and they will work reliably.
Contact information For more information, please visit: Sorry for the confusion. The problem is that generally you can detect a pin going to or from tristate OR transmit to the pin, but not both. It is neither qualified nor tested in accordance with automotive testing or application requirements.
Product details Documentation Support Ordering. All referenced brands, product names, service names and trademarks are the property of their respective owners. Revision history Table For more information, please visit: Recommended operating conditions Table 5. That works for outputs. A digital pin can drive 40mA, up to a total of mA. I just stumbled upon this thread again and got really embarrassed for not giving proper feedback. If available you can find information in our Nexperia Support Community or you can find Nexperia models and Design tools.
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.
The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables 1OE and 2OEeach controlling four of the 3-state outputs. What do you use?
