The NCT5914W is a 4-bit translating transceiver designed for 3.3V LVTTL system interface with a GTL-/GTL/GTL+ bus. The direction pin allows the part to function as either a GTL-to LVTTL or an LVTTL-to-GTL to GTL voltage level translator. The NCT5914W LVTTL input and direction pins are 5.5V tolerant, allowing direct access to TTL or 5V CMOS voltage inputs. GTL inputs and outputs operate up to 3.6V, allowing the device to be used in higher voltage open-drain output applications.
