PI4GTL2014 4-bit LVTTL to GTL transceiver Features Description  Operates as a 4-bit GTL − /GTL/GTL+ sampling receiver 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.  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 Pin Configuration PI4GTL2014 Document Number 40568 Rev1-2 Pin Description Pin Name Pin# DIR B0 B1 B2 B3 A0 A1 A2 A3 VREF GND VCC 1 2 3 5 6 13 12 10 9 4 7,8,11 14 www.diodes.com 1 Description Direction control input (LVTTL) Data inputs/outputs (GTL) Data inputs/outputs (LVTTL) GTL reference voltage Ground (0 V) Positive supply voltage January 2018 © Diodes Incorporated PI4GTL2014 Maximum Ratings Power supply.........................................................................................................-0.5V to +4.6V Voltage on an I/O pin .............................................................................GND-0.5V to +7.0V Supply current .................................................................................................................. ±160mA Ground supply current ......................................................................................................400mA Total power dissipation....................................................................................................200mW Operation temperature...................................................................................................-40~85℃ Storage temperature ................................................................................................... -65~150℃ Maximum Junction temperature ,T j(max) .................................................................. 125℃ Total power dissipation...................................................................................................200mW Note: Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device.
