As most fatasheet my peripheral circuits run on 5V, I need some way of level shifting. IEC logic symbol All information provided in this document is subject to legal disclaimers. That works for outputs. However, if it is soldered, the solder land should remain floating or be connected to GND.

Gert van der Knokke. I notice that the 74LVC8T mentioned above has a direction pin, and does not rely on auto-sensing.

Sample As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: Terms and conditions of commercial sale — NXP Semiconductors products are sold subject to the general terms and conditions of commercial sale, as published at http: Power supply can be 7h4ct244d to 5. Given that the LPC, and much other 3. Recommended operating conditions Table 5. Preliminary [short] data sheet Qualification This document contains data from the preliminary specification.

There is no dataeheet or mechanical requirement to solder this pad.

These are also nice level converters and in DIP package available too: For output direct connection without problems. For detailed and full information see the relevant full data sheet, which is available on request via the local NXP Semiconductors sales office. All information provided in this document is subject to legal disclaimers.

Sample orders normally take days for delivery. The LPC data sheet explains this in more detail. There is one dirty trick that many of us use. Functional description Table 3. I’d prefer a chip with lines, not necessarily bidirectional. As a result magic translators tend to have limited drive or are open-drain with a pull up.

The device can be used as two 4-bit buffers or one 8-bit buffer. 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.

So a 74 HCT is indeed the proper choice. Ordering information Table 1. Support Find answers to your design questions on this page. Contents 1 2 3 4 5 5. 74uct244d and hide this message. Normal logic-level output current is lower. While inputs are 5V tolerant, outputs are not.

But I wouldn’t 74hct244d on “typical” values if you want a robust design. Going to try some simple pullup resistors. Search Search Cross reference Parametric search. Find answers to your design questions on this page. In comparison a normal logic gate has well known logic levels and full drive capability so you won’t get tripped up by pull-up resistors or loading.

Limiting values Table 4. Ptot derates linearly with 5. Test circuit for measuring switching times Table 9. In case an individual 74hct244 is concluded only the terms and conditions of the respective agreement shall apply.

I have used the 74HC as logic converter, which worked flawlessly. I just stumbled upon this thread again and got really embarrassed for not giving proper feedback. Customers should provide appropriate 74hvt244d and operating safeguards to minimize the risks associated with their applications and products.

This document supersedes and replaces all information supplied prior to the publication hereof. However the mopst popular device in my arsenal, which will translate both ways, from a variety of voltages to a variety of voltages is the 74LVC8T
