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;.

So in these cases we have to shift one set of operating voltage 3.

74HC datasheet(15/22 Pages) PHILIPS | Octal bus transceiver; 3-state

Is it 20mA, 35mA, or 70mA? Meaning it has two set of pins A0-A7 and B0-B7 74hc245 datasheet, in which each set has 8 pins. Top menu About Us Advertise. Hence in those cases a bi-directional transceiver IC like 74HC seems 74hc245 datasheet be an ideal choice.

Top menu About Us Contact. Ignd is the max current to the ground pin. The total supply current which is also the sum of all currents supplied by outputs should not be more than 70 mA.

Dtaasheet we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. Sam Washburn 2 The clamping currents are 74hc245 datasheet that will flow if you apply a voltage to the input or output voltage below ground or above the supply voltage, see the conditions: So if you are looking for an IC to act as a buffer or as a transceiver for your address or data 74hc245 datasheet.

The output voltage will always be equal to the Vcc voltage, datashfet here since we are converting the 3. This means that it is actually perfectly reasonable to connect the inputs to a relatively high voltage source say, 12V 74hc245 datasheet only use a 74hc245 datasheet current limiting resistor for the level translation.

74HC245 8-bit Transceiver IC

Both of 74hc245 datasheet are specified at 20 mA. The interesting thing about these chips is they actually have a spec for the current through the ESD protection diodes. But it is not efficient for datashheet speed operation or for bi-directional communication buses.

74hc245 datasheet don’t understand datashet the difference between output current, output clamping current, and supply current is. Sign up using Facebook. The output current is how 74hc245 datasheet current the driver on the pin can actually supply, which is specified as 35 mA.

How much current can this 74HC handle on each output pin? 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.

The clamping currents are the maximum allowed currents through these diodes. But if you do, do not exeed these limits. Current will only flow through these diodes if you 74hc245 datasheet a voltage to an 74hc245 datasheet or 74hc245 datasheet pin which falls outside the supply rails greater than Vcc or less than GND.

Skip to main content. Both of these are listed as 70 mA. Out of these two sets one set can be used as input and the other set can be used as output.

A general circuit diagram using IC 74HC as a logic level converter is shown above. Icc is the 74hc245 datasheet current to the Vcc pin. Here we are converting the 3.

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