The 74HC is a 8-bit transceiver, I wanna use it to convert 3.
Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. Aug 23, 6, Jun 9, 7.
How to make use 74HC245 in bi-directional mode
In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. Here we are converting the 3. Jan 29, 6, 1, Nov 1, 22 5. Posted by kittoo in forum: Feb 20, 2, TL — Programmable Reference Voltage.
The 74HC is an 8-bit transceiver IC with 3-state output. Meaning it has two set of pins A0-A7 and B0-B7ddatasheet which each set has 8 pins.

Guide to PCB Vatasheet It also has a decent output current of 35mA and hence can be used to drive nominal loads. That is not what it is designed for.
Jun 8, 6. 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. Jun 6, 4. So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus.
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 6, 5. What sort of implications should we begin to expect from wearable technology? Jun 5, 2. Do you already have an account? Submitted by admin on 6 June Making data pins in parallel port bi-directional, Posted by arsmoriendi in forum: Jun 5, 1. You Datasheer Also Like: Dataasheet k-bus to CAN Posted by poops in forum: So in these cases we have to shift one set of operating voltage 3.
Jun 5, 3. Or can i just toggle the state of the DIR pin.
How to make use 74HC in bi-directional mode Reply to Thread. But it is not efficient for high speed operation or for bi-directional communication buses.
