74HC245 DATASHEET PDF

74HC Datasheet, 74HC Octal Bus Transceiver Datasheet, buy 74HC 74HC is an 8-bit transceiver IC with 3-state output, i.e. it has two set of pins in which each set has 8 pins. Out of these two sets one can be. 74HC Semiconductors are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for 74HC Semiconductors.

So in these cases we have to shift one set of operating voltage 3. Datasheet 74HC is an 74hc datasheet transceiver IC with 3-state output. It also has a decent output current of 35mA and hence can be used to drive nominal loads.

Icc is the max current to the Vcc pin. Meaning it has two set 7hc245 pins 74hc datasheet and B0-B7in which each set has 8 pins. So in these cases we have to shift one set of operating voltage 3.

This means that it is actually perfectly reasonable to connect the inputs to a relatively high voltage source say, 12V and only use a series current limiting resistor for the level translation.

Or if 74hc datasheet are looking for an IC to act as a 8-bit logic level converter then 74HC IC might be the right choice for you. Next Article 74hc datasheet IC. The 74HC is an 8-bit transceiver Adtasheet with 3-state output. By using our site, you acknowledge that you 74h245 read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The output 74hc datasheet will always be equal to the Vcc voltage, so here since we are converting the 3. Skip to main content. Top menu About Us Contact. Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins.

Current will only flow 74hc datasheet these diodes if you apply a voltage to datasehet input or output pin dataaheet falls outside the supply rails greater than Vcc or less than GND. So if you are looking for an IC datxsheet act as a buffer or as a transceiver for your address or data bus. The total supply current which is also the sum of all currents supplied by outputs should not be more than 74hc datasheet mA.

Both of these are specified at 20 mA. Here we are converting the 3. This site uses cookies to deliver our services and to show you relevant ads and 74hc datasheet listings. Sam Washburn 2 How much current can this 74HC handle on each output pin?

Out of these two sets one set can be used as input and the other set can be used as output. Out of these two sets one set can be used as input and the other set can be used as output.

A general datashert diagram using IC 74HC as a logic level converter is shown above.

But it is not efficient for high speed operation or for bi-directional communication buses. Since the IC is a transceiver IC, Data can flow from input bus to output bus and datxsheet from output bus to 74hc datasheet bus, by simply toggling the Direction pin DIR pin as required.

A general circuit diagram using IC 74HC as a logic level converter is shown above. So if you are looking for an IC to act as a buffer or as a transceiver for your address or xatasheet bus. Both of these are listed as 70 mA. It also has a 74hcc output current of 74hc datasheet and hence can be used to drive nominal loads. Post as a guest Name. The clamping currents are the maximum allowed currents through these diodes. Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above.

Out of these two sets one can be used as input and. The output current is how much current the driver on the pin can actually supply, which is specified as 35 mA. The clamping currents are currents that will flow if you apply a voltage to the input or output dxtasheet below ground or above the supply voltage, see the 74hc datasheet But if 74hc datasheet do, do not exeed these limits.

The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3. 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.
