74hctd datasheet & applicatoin notes – Datasheet Archive
The device can be used as two 4-bit buffers or one 8-bit buffer. Sorry for the confusion. Power supply can be 2 to 5. I notice that the 74LVC8T mentioned above has a direction pin, and does not rely on auto-sensing. But I wouldn’t rely on “typical” values if you want a robust design. Limiting values Table 4. But I attribute this to lack of coffee – I should have verified my claims: NXP Semiconductors makes no representation or warranty that such applications will be suitable for the specified use without further testing or modification.
The problem is that generally you can detect a pin going to or from tristate OR transmit to the pin, but not both.
The content is still under internal review and subject to formal approval, which may result in modifications or additions. Accept and hide this message. In comparison a normal logic gate has 74cht244d known logic levels and full drive capability so you won’t get tripped up by pull-up resistors or loading.
Gert van der Knokke. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. Non-automotive qualified products — Unless this data sheet expressly states that this specific NXP Semiconductors product is automotive qualified, the product is not suitable for automotive use.
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 While inputs are 5V tolerant, outputs are not. Sample orders normally take days for delivery. I just stumbled upon this thread again and got really embarrassed for not giving proper feedback.

Thanks all, with an added cheer for Hexley dominating the mbed challenge! I haven’t seen any logic level converter in DIP packages.
As a result magic translators tend to have limited drive or are open-drain with a pull up. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of V CC. Applications — Applications that are described herein for any of these products are for illustrative purposes only.

IEC logic symbol All information provided in this document is subject to legal disclaimers. You might choose the 74HCT — that would give you 8 lines in a single package.
Ptot derates linearly with 5. The English version shall prevail in case of any discrepancy between the translated and English versions. These are also nice level converters and in DIP package available too: Export might require a prior authorization from competent authorities. Limiting values — Stress above one or more limiting values as defined in the Absolute Maximum Ratings 74nct244d of IEC will cause permanent damage to the device.
The latest product status information is available on the Internet at URL http: Constant or repeated exposure to limiting values will permanently and irreversibly affect the quality and reliability of the device. Ordering information Table 1. Dynamic characteristics Table 7. There is no electrical or mechanical requirement to solder this pad.
Run HCT parts on 5V and directly drive the inputs from 3. Recommended operating conditions Table 5. Product [short] data sheet Production This document contains the product specification. Test circuit for measuring switching times Table 9.
