4-bit LVTTL to GTL transceiver

Rev. 01 — 19 May 2005

Product data sheet

1. General description

The GTL2014 is a 4-bit translating transceiver designed for 3.3 V LVTTL system interface

with a GTL−/GTL/GTL+ bus.

The direction pin allows the part to function as either a GTL to LVTTL sampling receiver or

as a LVTTL to GTL interface.

The GTL2014 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 GTL2014 GTL inputs and outputs operate up to 3.6 V, allowing the device to be used

in higher voltage open-drain output applications.

2. Features

■ Operates as a 4-bit GTL−/GTL/GTL+ sampling receiver or as a LVTTL to

GTL−/GTL/GTL+ driver

■ 3.0 V to 3.6 V operation with 5 V tolerant LVTTL input

■ GTL input and output 3.6 V tolerant

■ V_refadjustable from 0.5 V to V_CC/2

■ Partial power-down permitted

■ ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per

JESD22-A115, and 1000 V CDM per JESD22-CC101

■ Latch-up protection exceeds 500 mA per JESD78

■ Package offered: TSSOP14
