Feb 20, 2, Posted by kittoo in forum: Jun 9, 7. Quote of the day. What sort of implications should we begin to expect from wearable technology? Or can i just toggle the state of the DIR pin.
Jun 9, 8. Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. But it is not efficient for high speed operation or for bi-directional communication buses. Jun 5, 3. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider.
Your name or email address: Jan 29, 6, 1, The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3. It also has a decent output current of 35mA and hence can be used to drive nominal loads.

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. Guide to PCB Design: Aug 23, 6, Yes, my password is: Submitted by admin on 6 June So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus.
Also we 74uc245a reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. Nov 1, 22 5.

How to make use 74HC245 in bi-directional mode
Jun 6, 4. Irrespective of the direction, the output will be just about the Vcc level. Since the IC is a transceiver IC, 74hc254a 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.
The 74HC is an 8-bit transceiver IC with 3-state output. So in these cases we have to shift one set of operating voltage 3.
TL — Programmable Reference Voltage. How to make use 74HC in bi-directional mode Reply to Thread.
Jun 8, 6. Here we are converting the 3.
Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins.
