DESCRIPTION
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.
The enable pins allow the system control to disconnect the bus termination. When the bus switch is enabled, a 56, 75, 100 or 150 series resistance is connected to the GTL Vbias.
