Jun 5, 3. Your name or email address: TL — Programmable Reference Voltage. That is not what it is designed for. Submitted by admin on 6 June Or if you are looking for an IC to act as a 8-bit logic level converter then 74HC IC might be the right choice for you. Jun 6, 4. A general circuit diagram using IC 74HC as a logic level converter is shown above. What sort of 74gc245a should we begin to expect from wearable technology?

Jun 9, 8. Guide to PCB Design: Do you already have an account? Aug 23, 6, Jun 9, 7. It also has a decent output current of 35mA and hence can be used to drive nominal loads. You can’t use it as a bidirectional level converter.

Here we are converting the 3. So when I convert 3. Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins. Bi-directional k-bus to CAN Posted by poops in forum: Feb 20, 2, Jun 5, 1. Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice.

Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. Out of these two sets one set can be used as input and the other set can be used as output.

The 74HC is a 8-bit transceiver, I wanna use it to convert 3. DIR is only the direction.

No, create an account now. Jun 5, 2. You May Also Like: The 74HC is an 8-bit transceiver IC with 3-state output.

But it is not efficient for high speed operation or for bi-directional datashet buses. Nov 1, 22 5. How to make use 74HC in bi-directional mode Reply to Thread. Jun 6, 5.

Or can i just toggle the state of the DIR pin. Quote of the day. Irrespective of the direction, the output will be just about the Vcc level.

Posted by kittoo in forum: Jan 29, 6, 1, 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.

Sep 16, 59 4. So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus.

Jun 8, 6. Yes, my password is: So in these cases we have to shift one set of operating voltage 3. 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.

Making data pins in parallel port bi-directional, Posted by arsmoriendi in forum: Jun 9, 9. Oct 10, 1, Since the IC is a transceiver IC, Data can flow from input bus to output bus and also from output bus to input bus, by simply toggling the Direction pin DIR pin as required.
