PI4GTL2014

Features  Operates as a 4-bit GTL − /GTL/GTL+ sampling receiver or as a LVTTL to GTL − /GTL/GTL+ driver  2.3 V to 3.6 V operation with 5 V tolerant LVTTL input  GTL input and output 3.6 V tolerant  Vref adjustable from 0.5 V to VCC/2  Partial power-down permitted  ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-CC101  Latch-up protection exceeds 200 mA per JESD78  Package offered: TSSOP14 PI4GTL2014 4-bit LVTTL to GTL transceiver Description The PI4GTL2014 is a 4-bit translating transceiver designed for 3.3 V LVTTL system interface with a GTL − /GTL/GTL+ bus, where GTL − /GTL/GTL+ refers to the reference voltage of the GTL bus and the input/output voltage thresholds associated with it. The direction pin allows the part to function as either a GTL to LVTTL sampling receiver or as a LVTTL to GTL interface. The PI4GTL2014 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 PI4GTL2014 GTL inputs and outputs operate up to 3.6 V, allowing the device to be used in higher voltage open-drain output applications.
