TL — Programmable Reference Voltage. Making data pins in parallel port bi-directional, Posted by arsmoriendi in forum: A general circuit diagram using IC 74HC as a logic level converter is shown above.

Do you already have an account?

Irrespective of the direction, the output will be just about the Vcc level. Jun 5, 3. It also has a decent output current of 35mA and hence can be used to drive nominal loads. Jun 9, 7. The 74HC is an 8-bit transceiver IC with 3-state output.

Bi-directional k-bus to CAN Posted by poops in forum: Posted by kittoo in forum: No, create an account now. Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above.

74HC245 5V CMOS Octal Transceiver

So when I convert 3. Nov 1, 22 5. DIR is only the direction. Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. Jun 8, 6. Out of these datqsheet sets one set can be used as input and the other set can be used as output. That is not what it is designed for.

Data Sheets: 74HCREV1

So if you are dstasheet for an IC to act as a buffer or as a transceiver for your address or data bus. What sort of implications should we begin to expect from wearable technology? Jun 6, 5.

But it is not efficient for high speed operation or for bi-directional communication buses. Oct 10, 1, Feb 20, 2, Yes, my password is: Jun 9, 8. Jun 6, 4. 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 datashret the output voltage is equal to the voltage supplied to the Vcc pin.

Quote of the day. Jun 9, 9.

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

Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. How to make use 74HC in bi-directional mode Reply to Thread. Or can i just toggle the state of the DIR pin. You May Also Like:
