You can look at the data sheets how the logic high voltage is defined should be either 2 volts, 0.

74HCT244D Datasheet

Functional description Table 3. Table 7 on page 45 gives the following limits for standard port pins: Going the other direction, you may not need a translator — some mbed pins are 5-volt tolerant. The problem is that generally you can detect a pin going to or from tristate OR transmit to the pin, but not both.

For output direct connection without problems. Written HW 2 solutions.

Ordering information Table 1. That works for outputs. Gert van der Knokke. I tried several HCT buffer type parts and all of them worked! 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.

NXP Semiconductors makes no representation or warranty that such applications will be suitable for the specified use without further testing or modification. Translations — A non-English translated version of a document is for reference only.

As most of 74hct424d peripheral circuits run on 5V, I need some way of level daasheet. Sample orders normally take days for delivery. I’ve seen discrete versions of bidirectional level translators consisting of just one FET.

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 design.

Product details Documentation Support Ordering. Recommended operating conditions Table 5. Find answers to your design questions on this page. If your external devices are of 74HC or 74LS series, you can connect them safely and they will work reliably.

A digital pin can drive 40mA, up to a total of mA. If available you can find information in our Nexperia Support Community or you datashwet find Nexperia models and Design tools.

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. I’d prefer a chip with lines, not necessarily bidirectional.

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: And it’s available in an easy-to-use through-hole package. But I attribute this to lack of coffee – I should have verified my claims: Fatasheet Find answers to your design questions on this page.

Dagasheet 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. The substrate is attached to this pad using conductive die attach material. It is neither qualified nor tested in accordance with automotive testing or application requirements.

As Hendrik has found, it happens that HC parts also work much of the time, since at room temperature their “typical” spec for VIH actually falls below their guaranteed “minimum” spec of 3.
