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.

Short-form specification -- The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition -- Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
