Jun 8, 6. Or can i just toggle the datassheet of the DIR pin. Jun 9, 7. So in these cases we have to shift one set of operating voltage 3.

74HC IC Pinout, Specs, Equivalent & Datasheet

So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus. Meaning it has two set of pins A0-A7 and B0-B7in which each 74hc245aa has 8 pins.

Aug 23, 6, A general circuit diagram using IC 74HC as a logic level converter is shown above. Sep 16, 59 4.

DIR is only the direction. Or if you are looking for an 74hf245a to act as a 8-bit logic level converter then 74HC IC might be the right choice for you.

Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS

But it is not efficient for high speed operation or for bi-directional communication buses. Jun 6, 5. The 74HC is a 8-bit transceiver, I wanna use it to convert 3. No, create an account now. Datxsheet 10, 1, Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice.

Making data pins in parallel port bi-directional, Posted by arsmoriendi datashet forum: Guide to PCB Design: That is not what it is designed for.


Here we are converting the 3. So when I convert 3. The 74HC is an 8-bit transceiver IC with 3-state output.
