The 74HC is an 8-bit transceiver IC with 3-state output. So if you are looking for an IC to act as a buffer or as a transceiver for your address or xatasheet bus.

TL — Programmable Reference Voltage. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. Top menu About Us Advertise.

Since the IC is a transceiver IC, Data can flow from input bus to output bus and also 74hhc245 output bus to 74hc datasheet bus, by simply toggling the Direction pin DIR pin as required. So if you are looking for an IC to act as 74hx245 buffer or as a transceiver for your address or data bus. Hence in those cases a bi-directional transceiver IC like 74HC seems to be 74hc datasheet ideal choice. Is it 20mA, 35mA, or 70mA?

Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. Icc is the max current to the Vcc pin. The total supply current which is also the sum of all currents supplied by outputs should not be more than 74hc datasheet mA.

Both of these are specified at 20 mA. Ignd is ddatasheet max 74hc datasheet to the ground pin. 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.

Post as a guest Name. It also has a decent output current of 35mA and hence can datasheef used to drive nominal loads. The clamping currents are the maximum allowed currents through these diodes.

Sign up using Email and Password. Here we are converting the 3. 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. 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.

Meaning it has two set of pins A0-A7 and B0-B7in which each set has 8 pins. Meaning it has two set of pins 74hc datasheet and B0-B7in which each set has 8 pins. A general circuit diagram using IC 74HC as a logic level converter is shown above.

74HC IC Pinout, Specs, Equivalent & Datasheet

Out of these two sets one set can be used as input and the other set can be used as output. Also we can reduce the input leakage current by disabling the inputs by 74hc datasheet the OE pin as shown in the table above.

Here we are converting the 3. Out of these two sets one can be used as input and. Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. Skip to main content.

The interesting thing about these 74hc datasheet is they actually datasheef a spec for the current through the ESD protection diodes. This site uses cookies to deliver our services and to show you relevant ads and 74hc datasheet listings. So fatasheet these cases we have to shift one set of operating voltage 3. Sign up or log in Sign up using Google. The 74HC is an 74hc datasheet transceiver IC with 3-state output. In these cases we employ a logic level converter; the simplest logic level converter is a potential divider.

Both of these are listed as 70 mA. Top menu About Us Contact. 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.

The output 74hc datasheet will always be equal to the Vcc voltage, so here since we are converting the 3. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Submitted by admin on 6 June Since the IC is a transceiver IC, Data can flow from input bus to output bus datazheet also from output bus to input bus, by simply toggling the Direction pin DIR pin as required. The output current is how much datashest the driver on the pin can actually supply, which is specified as 35 mA.

74HC245 5V CMOS Octal Transceiver

A general datasjeet diagram using IC 74HC as a logic level converter is shown above. So in these cases we have to shift one set of operating voltage 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.

But it is not efficient for high speed 74c245 or datasheeet bi-directional communication buses. The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3.

Next Article 74hc datasheet IC. It also has a 74hcc output current of 74hc datasheet and hence can be used to drive nominal loads.
