General description

The GTL2014 is a 4-bit translating transceiver designed for 3.3 V LVTTL system interface with a GTL−/GTL/GTL+ bus.

The direction pin allows the part to function as either a GTL to LVTTL sampling receiver or as a LVTTL to GTL interface.

The GTL2014 LVTTL inputs (only) are tolerant up to 5.5 V allowing direct access to TTL or 5 V CMOS inputs. The LVTTL outputs are not 5.5 V tolerant.

The GTL2014 GTL inputs and outputs operate up to 3.6 V, allowing the device to be used in higher voltage open-drain output applications.
