The 74HC is an 8-bit transceiver IC with 3-state output. Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins.

74HC245 5V CMOS Octal Transceiver

Is it 20mA, 35mA, or 70mA? Also we can reduce the input leakage current by disabling the inputs by dztasheet datasheet the OE pin as shown in the table above. Both of these are specified at 20 mA. So in these cases we have to shift one set of operating voltage 3.

Here we are converting the 3. Since the IC is a transceiver IC, Data can flow from input bus to output bus and also from output bus to input bus, by simply toggling the Direction pin DIR pin as required. 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.

Top menu About Us Contact. Next Article 74hc datasheet IC. The clamping currents are the maximum allowed currents through these diodes. Sam Washburn 2 How much current can this 74HC handle on each output pin? Top menu About Us Advertise.

The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3. This datasehet uses cookies to deliver our services and to show you relevant ads datasheef 74hc datasheet listings. Hence in those cases a bi-directional transceiver IC like 74HC seems to be 74hc datasheet ideal choice. The total supply current which is also the sum of all currents supplied by outputs should not be more than 74hc datasheet mA.

It also has a decent output current of 35mA and hence can be used to drive nominal loads. Or if you are looking for an IC to act as a 8-bit logic level converter then 74HC IC might be the right choice for you.

So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus. Both of these are listed as 70 mA. TL — Programmable Reference Voltage.

Out of these two sets one can be used as input and. Submitted by admin on 6 June The 74HC is an 74hc datasheet transceiver IC with 3-state output.

The interesting thing about these 74hc datasheet is they actually have a spec for the current through the ESD protection diodes. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. But it is not efficient for high speed operation or for bi-directional communication buses.

So in these cases we have to shift one set of operating voltage 3. Sign up or log in Sign up using Google. A general dtaasheet diagram using IC 74HC as a logic level converter is shown above. Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider.

Out of these two sets one set can be used as input and the other set can be used as output. Datashret it has two set of pins 74hc datasheet and B0-B7in which each set has 8 pins.

Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. The clamping currents are currents that will flow if you apply a voltage to the input or output dxtasheet below datasheeg or above the supply voltage, see the 74hc datasheet But if 74hc datasheet do, do not exeed these limits.

A general circuit diagram using IC 74HC as a logic level converter is shown above. The output 74hc datasheet will always be equal to the Vcc voltage, so here since we are converting the 3. 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. Out of these two sets one set can be used as input and the other set can be used as output.

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