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.

Note:

Stresses greater than those listed under MAXIMUM

RATINGS may cause permanent damage to the

device. This is a stress rating only and functional

operation of the device at these or any other

conditions above those indicated in the operational

sections of this specification is not implied.

Exposure to absolute maximum rating conditions

for extended periods may affect reliability.

Note:

[1] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

[2] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which

are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
