1. General description
The GTL2005 is a quad translating transceiver designed for 3.3 V system interface with a
GTL/GTL+ bus.
The direction pin (DIR) allows the part to function as either a GTL-to-TTL sampling
receiver or as a TTL-to-GTL interface.
The GTL2005 LVTTL interface is tolerant up to 5.5 V allowing direct access to TTL or 5 V
CMOS outputs.
The GTL2005 V
ref
linearity degrades below 0.8 V (see Section 10.1). If the application
allows, use the GTL2014, otherwise more closely review noise margins.
