Revision history Table Search Search Cross reference Parametric search. HC, or look for some with schmitt-trigger. Test circuit for measuring switching times Table 9. In case of any inconsistency or conflict with the short data sheet, the full data sheet shall prevail. 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.

For detailed and full information see the relevant full 74htc244d sheet, which is available on request via the local NXP Semiconductors sales office. 74hvt244d your external devices are of 74HC or 74LS series, you can connect them safely and they will work reliably.

However, if it is soldered, the solder land should remain floating or be connected to GND. The device features two output enables 1 OE and 2 OEeach controlling four of the 3-state outputs.

So a 74 HCT is indeed the proper choice. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. The device features two output enables 1OE and 2OEeach controlling four of the 3-state outputs. Find answers to your design questions on this page.

You might choose the 74HCT — that would give you 8 lines in a single package. By disabling cookies, some features of the site will not work. 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.

Run HCT parts on 5V and directly drive the inputs from 3. 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: Contents 1 2 3 4 5 5.
