Bi-directional k-bus to CAN Posted by poops in forum: Sep 16, 59 4. Jan 29, 6, 1, I can use the DIR pin to toggle the direction of conversion according to this table below But what confuses me is that, people state that the output voltage is equal to the voltage supplied to the Vcc pin.

Out of these two sets one set can be used as input and the other set can be used as output. Your name or email address: Jun 6, 4. It also has a decent output current of 35mA and hence can be used to drive nominal loads.

How to make use 74HC in bi-directional mode | All About Circuits

So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus. So in these cases we have to shift one set of operating voltage 3.

Oct 10, 1, Irrespective of the direction, the output will be just about the Vcc level. Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. No, create an account now.

Making data pins in parallel port bi-directional, Posted by arsmoriendi in forum: Jun 9, 7. Jun 8, 6. Aug 23, 6, The 74HC is a 8-bit transceiver, 74hc245aa wanna use it to convert 3. Jun 5, 1. Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. So when I convert 3. Nov 1, 22 5.

Or can i just toggle the state of the DIR pin. Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 74hc245q. The 74HC is an 8-bit transceiver IC with 3-state output.

What sort of implications should we begin to expect from wearable technology? Submitted by admin on 6 June Posted by kittoo in forum: That is not what it is designed for.

Here we are converting the 3. The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. Jun 9, 9. Jun 9, 8. A general circuit diagram using IC 74HC as a logic level converter is shown above.
