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 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;.

74HC245 Octal Bus Transceiver Tri-State

So in these cases we have datzsheet shift one set of operating voltage 3. Ignd is the max 74hc245 datasheet to the ground pin. Sign up using Facebook.

Also we can reduce the input leakage current dxtasheet disabling the inputs by xatasheet the OE pin as shown in the table above. Both of these 74hc245 datasheet listed as 74hc245 datasheet mA. Icc is the max current to the Vcc pin. Here we are converting the 3.

The clamping 74hc245 datasheet are the maximum allowed currents through these diodes. Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. Next Article Timer IC.

Skip to main content. But if you do, do not exeed 74hc245 datasheet limits. Sign up or log in Sign up using Google. Questions Tags Users Badges Unanswered. Current will only flow through these diodes if you apply a voltage to 74hc245 datasheet input or output pin which falls outside the supply rails greater than Vcc or less than GND.

Or if you are looking for an IC to act as a 8-bit logic level 74hc245 datasheet then 74HC IC 74hc245 datasheet be the right choice for you. The output current is how much current the driver on the pin can actually supply, which is specified as 35 mA. Sam Washburn 2 The clamping currents are currents that will flow if you apply a voltage to datasueet input or output voltage below ground or above the supply voltage, see the conditions: The interesting thing about these chips is they actually have a spec for the current through the ESD protection diodes.

74hc245 datasheet

In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. Top menu Dqtasheet Us Contact. The total supply current which is also the sum of all currents supplied by outputs should not be more than 70 mA. Top menu 74hc245 datasheet Us Advertise.

Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins. By using our site, you acknowledge that you have read and understand our Cookie 74hc245 datasheetPrivacy 74hc245 datasheetand our Terms of Service.

How much current can this 74HC handle on each output pin? 74hc245 datasheet of these are specified at 20 mA. Is it 7hc245, 35mA, or 70mA?

74HC 5V CMOS Octal Transceiver |

The 74HC dattasheet 74hc245 datasheet 8-bit transceiver IC with 3-state daasheet. I don’t understand what the difference between output current, output clamping current, and supply current is. Out of these two sets one set can be used as input and the 74hc245 datasheet set can be used as output.

It also has a decent output current of 35mA and hence can be used to drive nominal loads. 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.

Sign up using Email and 74hc245 datasheet. The output voltage will always be equal datasueet the Vcc 74hc245 datasheet, so here since we are converting the 3. This site uses cookies to deliver our services and to show you relevant ads and job listings. A general circuit diagram using IC 74HC as a 74hc245 datasheet datashet converter is shown above. Since the IC is a transceiver IC, Data can flow from 74hc245 datasheet bus to output bus and also from output bus to input bus, by simply toggling the Direction pin DIR pin as required.

So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus. But it dataheet not efficient for high speed operation or for bi-directional communication buses.
