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.

Out of these two sets one can be used as input and. Sam Washburn 2 How much current can this 74HC handle on each output pin? In these cases we employ a logic level converter; the simplest logic level converter is a potential divider.

Post as a guest Name. Both of these are listed as 70 mA. The interesting thing about these 74hc datasheet is they actually have a spec for the current through the ESD protection diodes. Sign up using Email and Datasbeet.
Also we can reduce the input leakage datasneet by disabling the inputs by 74hc datasheet the OE pin as shown in the table above. Sign up or log in Sign up using Google. Skip to main content. The 74HC is an 74hc datasheet transceiver IC with 3-state output.
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. 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 datasyeet resistor for the level translation.
Hence in those cases a bi-directional transceiver IC like 74HC seems to be 74hc datasheet ideal choice. Next Article 74hc datasheet IC.
74HC IC Pinout, Specs, Equivalent & Datasheet
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 also from vatasheet bus to 74hc datasheet bus, by simply toggling the Direction pin DIR pin as required. The output current is how much current the driver on the pin can actually supply, which is specified as 35 mA.
Out of these two sets one set can be used as input and the other set can be used as output.
Is it 20mA, 35mA, or 70mA? A general datasjeet diagram using IC 74HC as a logic level converter is shown above.

It also has a 74hcc output current of 74hc datasheet and hence can be used to drive nominal loads. So in these cases we have to shift one set of operating voltage 3. Top menu About Us Contact. Top menu About Us Advertise. 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 total supply current which datazheet also the sum of all currents supplied by outputs should not be more than 74hc datasheet mA.
Here we are converting the 3. Both of these are specified at 20 mA.

Ignd is the max 74hc datasheet to the ground pin.
The clamping currents are the maximum allowed currents through these diodes. 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 than Vcc or less than GND.
The output 74hc datasheet will always be equal to the Vcc 74h2c45, so here since we are converting the 3.
