What is an octal buffer?
This octal buffer or line driver is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This device provides inverting outputs and symmetrical active-low output-enable (OE) inputs.
What is ic 74244?
74244 IC 8-Bit Buffer Chips used to drive data onto a 8-bit data bus. The functional IC is split into two 4-bit sections, so they could be operated together or separately, driving one 8-bit bus or two separate 4-bit buses.
What is the function of IC 74LS244?
The 74LS244 buffers/line drivers are designed to improve both the performance and PC board density of 3-STATE buffers/ drivers employed as memory-address drivers, clock drivers, and bus-oriented transmitters/receivers.
What is 74HC244?
General description. The 74HC244; 74HCT244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs.
What do you mean by tri-state buffer?
A tri-state buffer is a logic inverter or a non-inverting buffer with a tri-state output stage. When the enable line is not activated the buffer output stage has a high output impedance (i.e., the Z state, as described above in section 10.15) and transmission of data is prevented.
What is bidirectional buffer?
A bidirectional buffer circuit includes a first terminal, a second terminal, a first output buffer to which a signal from the first terminal is input and which outputs the signal to the second terminal, a first one-shot buffer control circuit outputting a first control signal according to an earlier arriving signal out …
What is 74HC series?
The 74HC family of logic devices are high speed, low power devices that use CMOS circuitry. The devices are pin compatible with many existing devices such as the 74TTL, 74STTL and 4000 series.
How a normal buffer is different from a tri-state buffer?
A tri-state buffer is similar to a buffer, but it adds an additional “enable” input that controls whether the primary input is passed to its output or not. If the “enable” inputs signal is true, the tri-state buffer behaves like a normal buffer.
How decoder is used in three-state buffer?
To form a single bus line, all the outputs of the 4 buffers are connected together. The control input will now decide which of the 4 normal inputs will communicate with the bus line. The decoder is used to ensure that only one control input is active at a time. The diagram of a 3-state buffer can be seen below.
When it is important to use a tri-state buffer?
The Tri-state Buffer is used in many electronic and microprocessor circuits as they allow multiple logic devices to be connected to the same wire or bus without damage or loss of data. For example, suppose we have a data line or data bus with some memory, peripherals, I/O or a CPU connected to it.
