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

Package offered: TSSOP14
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.
