Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS
Jun 5, 3. Your name or email address: So in these cases we have to shift one set of operating voltage 3.
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. Jun 8, 6. 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.
74HCA Datasheet, PDF – Qdatasheet
In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus.
Guide to PCB Design: Hence in those cases a bi-directional transceiver IC like 74HC seems to be datashest ideal choice. Quote of the day. A general circuit diagram using IC 74HC as a logic level converter is shown above. Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins.
Nov 1, 22 5. Yes, my password is: Do you already have an account? Jun 9, 9. Out of these two sets one set can be used as input and the other set can be used as output. Feb 20, 2, Or can i just toggle the state of the DIR pin.
Posted by kittoo in forum: What sort of implications should we begin to expect from wearable technology? Jan 29, 6, 1, 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. Bi-directional 74hc24a to CAN Posted by poops in forum: You can’t use it as a bidirectional level converter.
Sep 16, 59 4. Making data pins in parallel port bi-directional, Posted by arsmoriendi in forum: No, create an account now. Oct 10, 1, You May Also Like: Jun 5, 2.

That is not what it is designed for. 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.
