You can look at the data sheets how the datashheet high voltage is defined should be either 2 volts, 0. For detailed and full information see the relevant full data sheet, which is available on request via dtasheet local NXP Semiconductors sales office.
But I wouldn’t rely on “typical” values if you want a robust design. Written HW 2 solutions. Ordering information Table 1.
And it’s available in an easy-to-use through-hole package. I’ve seen discrete versions of bidirectional level translators consisting of just one FET.
Please, contact us at support mbed. Thanks all, with an added cheer for Hexley dominating the mbed challenge!
Power supply can be 2 to 5. You might choose the 74HCT — that would give you 8 lines in a single package. Customers should provide appropriate design and operating safeguards to minimize the risks associated with their applications and products. The substrate is attached to this pad using conductive die attach material. By disabling cookies, some features of the site will not work. Actually, it’s just the opposite.

Translations — A non-English translated datashee of a document is for reference only.

The device features two output enables 1 OE and 2 OEeach controlling four of the 3-state outputs. That works for outputs.
As a result magic translators tend to have limited drive or are open-drain with a pull up. The LPC data sheet explains this in more detail.

As most of my peripheral circuits run on 5V, I need some way of level shifting. 74hct2244d English version shall prevail in case of any discrepancy between the translated and English dahasheet.
For output direct connection without problems. Export might require a prior authorization from competent authorities. Contents 1 2 3 4 5 5. In case an individual agreement is concluded only the terms and conditions of the respective agreement shall apply.
I just stumbled upon this thread again and got really embarrassed for not giving proper feedback. The problem is that generally you can detect a pin going to or from tristate OR transmit to the pin, but not both. HC, or look for some with schmitt-trigger. Constant or repeated exposure to limiting values will permanently and irreversibly affect the quality and reliability of the device. Going the other direction, you may dstasheet need a translator — some mbed pins are 5-volt tolerant.
