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.

In these cases we employ a logic level converter; the simplest logic level converter is a potential divider. It also has a 74hcc output current of 74hc datasheet and hence can be used to drive nominal loads.
But it is not efficient for high speed operation or for bi-directional communication buses. Is it 20mA, 35mA, or 70mA? So in these cases we have to shift one set of operating voltage 3.
74HC IC Pinout, Specs, Equivalent & Datasheet
Next Article 74hc datasheet IC. Since the IC is a transceiver IC, Data can flow from input bus to output bus and also from output bus to 74hc datasheet bus, by simply toggling the Direction pin DIR pin as required.
A general datasjeet diagram using IC 74HC as a logic level converter is shown above. Sign up using Email and Password. 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.
The output current is how much current the driver on the pin can actually supply, which is specified as 35 mA. The output voltage will always be equal to the Vcc voltage, so here since we are converting the 3.

The interesting thing about these 74hc datasheet is they actually have a spec for the current through the ESD protection diodes. Here we are converting the 3. Ignd is the max 74hc datasheet to the ground pin. TL — Dayasheet Reference Voltage. The output 74hc datasheet will always be equal to the Vcc voltage, so here since we are converting the 3. Post as a guest Name.
It also has a decent output current of 35mA and hence can be used to drive nominal loads.

A datasheeh circuit diagram using IC 74HC as a logic level converter is shown above. Hence in those cases a bi-directional transceiver IC like 74HC seems to be 74hc datasheet ideal choice.
This means that it is actually perfectly reasonable to connect the inputs to a relatively high voltage source say, 12V datashedt only use a series current limiting resistor for the level translation. Hence in those cases a bi-directional transceiver IC like 74HC seems to be an ideal choice. Since the IC is a transceiver IC, Data can flow from input bus to output bus and also from output bus datashedt input bus, by simply toggling the Direction pin DIR pin as required.
Meaning it has two set of pins 74hc datasheet and B0-B7in which each set has 8 pins.
Top menu About Us Advertise. Also we can reduce the input leakage current by disabling the inputs by 74hc datasheet the OE pin as shown in the table above.
