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.

Hence datassheet 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.

The output current is how much current the driver on the pin can actually supply, which is specified as 35 mA. The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3. Sign up or log in Sign up using Google.

In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider.

Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins. Meaning it has two set of pins 74hc datasheet and B0-B7in which each set has 8 pins. Since the IC is a transceiver IC, Data can flow from input bus to output bus and also from output bus to 74hc datasheet bus, by simply toggling the Direction pin DIR pin as required.

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

74HC IC Pinout, Specs, Equivalent & Datasheet

Sam Washburn 2 How much current can this 74HC handle on each output pin? Both of these are specified at 20 mA. The total supply current which is also 74h245 sum of all currents supplied by outputs should not be more than 74hc datasheet mA.

Dataheet as a guest Name. So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus.

74HC245 5V CMOS Octal Transceiver

It also dtasheet a 74hcc output current of 74hc datasheet and hence can be used to drive nominal loads. Also we can reduce the input leakage current by disabling the inputs by 74hc datasheet the OE pin as shown in the table above.

Skip to main content. The clamping currents are the maximum allowed currents through these diodes. The 74HC is an 8-bit transceiver IC with 3-state output. Top menu About Us Contact. Icc is the max current to the Vcc pin.

So in these cases we have to shift one set of operating voltage 3. But it is not efficient for high speed operation or for bi-directional communication buses. Current will only flow 74hc datasheet these diodes if you apply a voltage to an input or output pin dataaheet falls outside the supply rails greater datashewt Vcc or less than GND.

Submitted by admin on datzsheet June Both of these are listed as 70 mA. Ignd is the max 74hc datasheet to the ground pin. Is it 20mA, 35mA, or 70mA? Or if you are looking for an IC to act as a 8-bit logic level converter then 74HC IC might be datwsheet right choice for you. Out of these two sets one set can be used as input and the other set can be used as output. Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above.

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. So in these cases we have to shift one set of operating voltage 3. A general datasjeet diagram using IC 74HC as a logic level converter is shown above.

TL — Programmable Reference Voltage. This site uses cookies to deliver our services and to show you relevant ads and 74hc datasheet listings. 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.

The 74HC is an 74hc datasheet transceiver IC with 3-state output.

Here we are converting the 3. A general circuit diagram using IC 74HC as a logic level converter is shown above. Here we are converting the 3. Or if 74hc datasheet are looking for an IC to act as a 8-bit logic level fatasheet then 74HC IC might be the right choice for you.
