A general circuit diagram using IC 74HC as a logic level converter is shown above. Aug 23, 6, Here we are converting the 3. Jun 9, 9. Making data pins in parallel port bi-directional, Posted by arsmoriendi in forum: You May Also Like: How to make use 74HC in bi-directional mode Reply to Thread.

Nov 1, 22 5. Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins.

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. It also has a decent output current of 35mA and hence can be used to drive nominal loads. Your name or email address: The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3.

dtaasheet Jun 8, 6. The 74HC is a 8-bit transceiver, I wanna use it to convert 3. TL — Programmable Reference Voltage. Do you already have an account?

Jun 5, 3. I can use the DIR pin to toggle the 74hc254a 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. Irrespective of the direction, the output will be just about the Vcc level.

Out of these two sets one set can be used as input and the other set can be used as output. Jun 9, 7.

So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus. Oct 10, 1, No, create an account now. Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice.

Jun 9, 8. That is not what it is designed for.

Posted by kittoo in forum: Jan 29, 6, 1, In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. You can’t use it as a bidirectional level converter. Or can i just toggle the state of the DIR pin. Quote of the day. Jun 6, 5. But it is not efficient for high speed operation or for bi-directional communication buses.

Bi-directional k-bus to CAN Posted by poops in forum: Submitted by admin on 6 June What sort of implications should we begin to expect from wearable technology? Sep 16, 59 4. 7hc245a 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.

Yes, my password is: Jun 5, 1. Also we can reduce the input leakage current by datashfet the inputs by using the OE pin as shown in the table above.
