The GTL202x series are 32-bit bus switches with GTL termination
and octal output enables. The GTL202x is intended to provide GTL
bus termination in multi-processor environments.
A17 18
A18 19
The enable pins allow the system control to disconnect the bus
termination. When the bus switch is enabled, a 56, 75, 100 or 150 Ω
series resistance is connected to the GTL Vbias.
