Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS

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 that the output voltage is equal to the voltage supplied to the Vcc pin. 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.

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. Jun 9, 7. What sort of implications should we begin to 74hd245a from wearable technology?


Quote of the day. Jun 6, 5. So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus.

Data Sheets

Oct 10, 1, Jun 8, 6. Guide to PCB Design: DIR is only the direction. You May Also Like: Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice.

Or if you are looking for an IC to act as a 8-bit logic level datasbeet then 74HC IC might be the right choice for you.

How to make use 74HC in bi-directional mode Reply to Thread. Irrespective of the direction, the output will be just about the Vcc level. That is not what it is designed for. So in these cases we have to shift one set of operating voltage 3.

Jun 5, 1. Daatsheet we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. Jun 6, 4. Your name or email address: In these cases we employ a logic level converter; the simplest logic level converter is a potential divider.


Posted by kittoo in forum: Jan 29, 6, 1, The 74HC is a 8-bit transceiver, I wanna use it to convert 3. Or can i just toggle the state of the DIR pin.

Jun 5, 2. Sep 16, 59 4. Yes, my password is: Submitted by admin on 6 June The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3. Nov 1, 7hc245a 5.

TL — Programmable Reference Voltage. No, create an account now. But datassheet is not efficient for high speed operation or for bi-directional communication buses.
