16-Bit Buffer IC Chips
Buffers are normally used to buffer, drive or separate one circuit from another. As in driving more loads than the original source IC could, driving the signals over a longer distance, or driving the signal off board to another PCB.
16-Bit Buffer Circuit
IC 16-Bit Buffer. used to drive data onto a 16-bit data bus. Note that the chip displayed indicates OE control of the output. So the outputs could be taken tri-state if required. The functional IC is split into two 8-bit sections, so they could be operated together or separately, driving one 16-bit bus or two separate 8-bit buses.
16-Bit Buffer by Function:
Note in most cases when a 74xx device is listed, a 54xx device is also available.
74xx represents the commercial temperature range and 54xx represents the industrial temperature range [IC Prefixes].
Example part numbers
54ABT125; Quadruple Bus Buffer Gates With 3- State Outputs
54ABT827; 10-Bit Buffers/Drivers With 3-State Outputs
54ALS244; Octal Buffers And Drivers With 3-State Outputs, 74244
54ALS241; Octal Buffers/Drivers With 3-State Outputs
Buffers may have inverting or non-inverting outputs. A few buffer ICs offer both options, although only with the smaller quad output sizes.
