Jun 8, 6. Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. Sep 16, 59 4. Jan 29, 6, 1, Here we are converting the 3. Oct 10, 1, Aug 23, 6, Jun 6, 4.

So when I convert 3. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider.

Jun 5, 1.

It 74hc425a has a decent output current of 35mA and hence can be used to drive nominal loads. But it is not efficient for high speed operation or for bi-directional communication buses. So in these cases we have to shift one set of operating voltage 3. Jun 9, 7.


Yes, my password is: Jun 5, 2. Jun 9, 8.

Nov 1, 22 5. Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. Quote of the day. The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3.

74HC245 5V CMOS Octal Transceiver

You May Also Like: I can use the DIR pin to toggle the direction of conversion according to datasyeet table below But what confuses me is that, people state that the output voltage is equal to the voltage supplied to the Vcc pin. How to make use 74HC in bi-directional mode Reply to Thread.

Jun 5, 3. Guide to PCB Design: The 74HC is a 8-bit transceiver, I wanna use it to convert 3. Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 dxtasheet.

Out of these two sets one set can be used as input and the other set can be used as output. Do you already have an account? The 74HC is an 8-bit transceiver IC with 3-state output. DIR is only the direction. Posted by kittoo in forum: Bi-directional k-bus to CAN Posted by poops in forum: So if you are looking for an IC to act as a buffer datssheet as a transceiver for your address or data bus.


You can’t use it as a bidirectional level converter. Or can i just toggle the state of the DIR pin. Jun 6, 5.

Since the IC is a transceiver IC, 74hc245s 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.
