Yes, my password is: Do you already have an account? Feb 20, 2, You can’t use it as a bidirectional level converter. Submitted by admin on 6 June Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice.

TL — Programmable Reference Voltage. Bi-directional k-bus to CAN Posted by poops in forum: How to make use 74HC in bi-directional mode Reply to Thread.

Meaning it has two set of datasneet A0-A7 and B0-B7in which each set has 8 pins. What sort of implications should we begin to expect from wearable technology? Jun 5, 1. Jun 6, 5.

Data Sheets: 74HCREV1

DIR is only the direction. Out of these two sets one set can be used as input and the other set can be used as output.

Jun 8, 6. Irrespective of the direction, the output will be just about the Vcc level. You 74c245a Also Like: 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. Sep 16, 59 4.

Here we are converting the 3. Or can i just toggle the state of the DIR pin. I can use the DIR pin to toggle the direction of conversion according to this table below But what 74hc245 me is that, people state that the output voltage is equal to the voltage supplied to the Vcc pin. Posted by kittoo in forum: Jun 9, 7. Nov 1, 22 5. Jun 9, 8.

That is not what it is designed for. The 74HC is a 8-bit transceiver, I wanna use it to convert 3. So in these cases we have to shift one set of operating voltage 3.

But it is not efficient for high speed operation or for bi-directional communication buses. So when I convert 3.

Also we can reduce the input leakage current by disabling dtaasheet inputs by using the OE pin as shown in the table above. Oct 10, 1, Jun 5, 2. Jun 6, 4. Jun 5, 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. The 74HC is an 8-bit transceiver IC with 3-state output.

Making data pins in parallel port bi-directional, Posted by arsmoriendi in forum: 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. So if you are looking for an IC to act as a dataaheet or as a datasheeg for your address or data bus.

No, create an account now. It also has a decent output current of 35mA and hence can be used to drive nominal loads. Jan 29, 6, 1, Guide to PCB Design: A general circuit diagram using IC 74HC as a logic level converter is shown above.
