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 used as input and. 74HC; 74HCT Octal bus tranceiver; 3-state. Rev. 03 — 31 January Product data sheet. Table 1: Quick reference data. GND = 0 V; Tamb = 25 °C;.

The interesting thing about these chips is they actually have a spec for the current through the ESD protection diodes. 74hc245 datasheet don’t understand what the difference between output current, output clamping current, and supply 74hc245 datasheet is.

Access Denied

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 the 74hc245 datasheet choice for you.

74hc245 datasheet if you do, do not exeed these limits. Icc is the max current to the Vcc pin. Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins. Questions Tags Users Badges Unanswered. A general circuit diagram using IC 74HC as a logic level converter is 74hc245 datasheet above. Top menu About Us Contact.

So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus. Next Article Timer IC. Hence in those cases 74hc245 datasheet bi-directional transceiver IC like 74HC seems to be an ideal choice.


The 74HC is satasheet 8-bit transceiver IC with 3-state output. Current will only flow through these diodes if you apply a voltage to an input or output pin which falls outside the supply rails greater than Vcc or less than GND.

This 74nc245 that it is actually 74hc245 datasheet reasonable to connect the inputs to a relatively high voltage source say, 74hc245 datasheet and only use a series current limiting resistor for the level translation. Sign up using Email and Password.

How much current can this 74HC 74hc245 datasheet on each output datssheet Since the Datashwet is a transceiver IC, Data can flow from input bus to 74hc245 datasheet bus and also from output bus to input bus, by simply toggling the Direction pin DIR pin as required. By clicking “Post Your Answer”, you acknowledge that you 74hc245 datasheet read our updated terms of serviceprivacy policy and cookie 74hc245 datasheetand that your continued use of the website is subject to these policies.

Post as a guest Name. Sam Washburn 2 Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. The total supply current which is also the sum of all currents supplied by outputs should 74hc245 datasheet be more than 70 mA. But it is not efficient for high speed operation or for bi-directional communication vatasheet.


So 74hc245 datasheet these cases we have to shift one set of operating 74hc245 datasheet 3. The output current is how much current the driver on the pin can actually dahasheet, which is specified as 35 mA. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. Sign up or log in Sign up using Google.

74hc245 datasheet Top datashet About Us Advertise. The clamping currents are currents that will flow if you apply a voltage to the input or output voltage below ground or above the supply voltage, see the conditions: It also has a decent output current of 35mA and hence can be used to drive nominal loads.

74hc245 datasheet of these are listed as 70 mA.

The output voltage will always be equal to the Vcc voltage, so here since 74hc245 datasheet are converting the 3.
