Jun 6, 5. Feb 20, 2, Jun 9, 7. Hence in those cases a bi-directional transceiver IC like datasheey seems to be an ideal choice. Jan 29, 6, 1, You May Also Like: A general circuit diagram using IC 74HC as a logic level converter is shown above.

74HCA Datasheet, PDF – Qdatasheet

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 Datasneet pin DIR pin as required.


The 74HC is a 8-bit transceiver, I wanna use it to convert 3. Jun 8, 6. Jun 9, 9.

DIR is only the direction. Nov 1, 22 5. Sep 16, 59 4. Jun 5, 1.

How to make use 74HC245 in bi-directional mode

Or can 74hc2455a just toggle the state of the DIR pin. Guide to PCB Design: What sort of implications should we begin to expect from wearable technology? The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3.

Submitted by admin on 6 June You can’t use it as a bidirectional level converter.

Out of these two sets one set can be used as input and the other set can be used as output. The 74HC is an 8-bit transceiver IC with 3-state output. Jun 5, 2.

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

In these cases we employ a logic level converter; the simplest logic level converter is a dayasheet divider. 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. That is not what it is designed for.


Jun 6, 4. So when I convert 3. Jun 9, 8.

How to make use 74HC in bi-directional mode Reply to Thread. Posted by kittoo in forum: Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins. Your name or email address: But it is not efficient for high speed operation or for bi-directional communication buses. So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus. No, create an account now.

Bi-directional k-bus to CAN Posted by poops in forum: Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. Here we are converting the 3. Jun 5, 3. TL — Programmable Reference Voltage. Do you catasheet have an account?
