Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Products conform to specifications per the terms of Texas Instruments standard warranty.

Tags Esquema e software de These chips have convenient pin-outs separating the input side from the output side. The package thermal impedance is calculated in accordance with JESD This package can be hermetically sealed with a metal lid.

Not recommended for new designs. Datashedt are datasheet of these on a single chip. Efforts are underway to better integrate information from third parties. Along the way I’ll also cover some additional chip characteristics that can be useful in complex designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.

Microcontrolador Microcontrolador Two-input logic gates The five standard two-input logic gates in the 74LS00 family are listed in dztasheet table below. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. Production processing does not necessarily include testing of all parameters. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.

The correct term for this is “high-impedance,” often shortened to “high-Z.

The five standard two-input logic gates in the 74LS00 family are listed in the table below. Many of the basic logic functions are also available in parts with “open collector” outputs.


In no event shall TI’s liability arising out of such information exceed the total purchase price of the TI part s at issue in this document sold by TI 74ld541 Customer on an annual basis. The 74LS is an eight-bit datasbeet latch, while the 74LS is an eight-bit edge-triggered latch. Esquema e software de grava CL includes probe and jig capacitance.

On all other products, production processing does not necessarily include testing of all parameters. These four-bit counter parts can count up or down.

TI assumes no liability for applications assistance or customer product design. This drawing is subject to change without notice.

The eight-bit buffers 74LS and 74LS are functionally equivalent to the widely used 74LS and 74LS; however the ‘ and ‘ have a more confusing pin-out to trip the unwary student. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

TI bases its knowledge and belief on information provided by third parties, and makes no representation or warranty as to the accuracy of such information. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. This arrangement greatly facilitates printed circuit board layout. The 3-state control gate is a 2-input NOR gate such that, if either output-enable OE1 or OE2 input is high, all eight outputs are in the high-impedance state.

This section introduces a number of useful digital logic chips for use in a variety of projects. Because tri-state buffers have many applications in microprocessor circuits, there are several useful chips available which are designed to function on eight data signals bits at one time.

Since open collector is often used where “0” is the active state, this is also called a “wired-OR” connection, referring to datashfet active-low OR function. These can be used in cases where the final output of a logic function only needs to sink current; a later section will give examples where this can be used.

A tri-state buffer or inverting buffer looks like a regular buffer or inverter, except there is an additional “enable” control signal entering the gate.

Body dimensions do not include mold flash or protrusion not to exceed 0, Although less common, there are decimal versions of these chips. Product device recommended for new designs.
