Direction Buffers

These buffers control the direction in which data information travels.

The GPIB-COM is interfaced to the IEEE-488 bus by National Semiconductor 75160A and

75162A transceivers. These integrated circuits are specifically designed to provide power-

up/power-down bus protection (glitch-free). The GPIB-COM counts as one IEEE-488 bus load,

thereby allowing an additional 14 devices to be connected before exceeding the bus loading

restrictions imposed by the IEEE-488.
