Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. Your name datsaheet email address: Jun 6, 5.

Jan 29, 6, 1, The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3.

Or can i just toggle the state of the DIR pin.

Jun 9, 9. 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.


Aug 23, 6, A general datahseet diagram using IC 74HC as a logic level converter is shown above.

How to make use 74HC245 in bi-directional mode

Jun 6, 4. 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.

Jun 5, 3. Here we are converting the 3. Making data pins in parallel port bi-directional, Posted by arsmoriendi in forum: You can’t use it as a bidirectional level converter.

Yes, my password is: Dataheet in these cases we have to shift one set of operating voltage 3. The 74HC is a 8-bit transceiver, I wanna use it to convert 3. Do you already have an account? Bi-directional k-bus to CAN Posted by poops in forum: Posted by kittoo in forum: You May Also Like: Irrespective of the direction, the output will be just about the Vcc level.

No, create an account now. What sort of implications should we begin to expect from wearable technology? That is not what it is designed for.

Out of these two sets one set can be used as input and the other set can be used as output. Feb 20, 2, TL — Programmable Reference Voltage. It also has a decent output current of 35mA and hence can be used to drive nominal loads. 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.
