Sep 16, 59 4. DIR is only the direction. Making data pins in parallel port bi-directional, Posted by arsmoriendi 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. Datwsheet the IC is a transceiver IC, Data can flow from input bus to output bus and also from output bus to input bus, 7h4c245a simply toggling the Direction pin DIR datasbeet as required.

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. Jun 9, 9. But it is not efficient for high speed operation or for bi-directional communication buses.

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. Irrespective of the direction, the output will be just about the Vcc level.

Datasheet «MC54/74HC245A»

It also has 74jc245a decent output current of 35mA and hence can be used to drive nominal loads. Jan 29, 6, 1, A general circuit diagram using IC 74HC as a logic level converter is shown above. The 74HC is a 8-bit transceiver, I wanna use it to convert 3. Jun 5, 1. 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. Your datashewt or email address: Feb 20, 2, Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins.

Jun 9, 8. Hence in those cases a adtasheet transceiver IC like 74HC seems to be an ideal choice. The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3. Out of these two sets one set can be used as input and the other set can be used as output.
