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. 74HC Semiconductors are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for 74HC Semiconductors.

Also we can reduce the input leakage current by disabling the inputs by using the OE pin as shown in the table above. Hence in those cases a bi-directional transceiver IC like 74HC seems to be 74hc datasheet ideal choice. The 74HC is an 8-bit transceiver IC with 3-state output. Skip to main content. In these cases we employ a logic level converter; the simplest logic vatasheet converter is a potential divider.

It also has a decent output current of 35mA and hence can be used to drive nominal loads. The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3. But it is not efficient for high speed operation or for bi-directional communication buses. 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.

TL — Programmable Reference Voltage. Meaning it has two set of pins 74hc datasheet and B0-B7in which each set has 8 pins. Post as a guest Name.

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. So if you are looking for an IC to act as a buffer or as a transceiver for your address or data bus. Out of these two sets one set can be used as input and the other set can be used as output. 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 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.

Sign up using Email and Password. Submitted by admin on 6 June 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. The 74HC is an 74hc datasheet transceiver IC with 3-state output.

The clamping currents are the maximum allowed currents through these diodes. The output 74hc datasheet will always be equal to the Vcc voltage, so here since we are converting the 3. Ignd is the max 74hc datasheet to the ground pin.

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.

A general datasjeet diagram using IC 74HC as a logic level converter is shown above. Out of these two sets one can be used as input and. But it is not efficient for high speed operation or for bi-directional communication buses.

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.

Out of these two sets one set can be used as input and the other set can be used as output. 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.

A general circuit diagram using IC 74HC as a logic level converter is shown above. This site uses cookies to deliver our services and to show you relevant ads and 74hc datasheet listings.
