translation without directional control

Unlike level-shifting bus switches, which only translate between fixed voltages, these bidirectional

low-voltage translators can translate any voltage between 1 and 5 V to any other voltage between

1 and 5 V. They also reduce ON-state resistance and minimize propagation delay.

The NXP family of Gunning Transceiver

Logic (GTL) bidirectional low-voltage

translators includes the 22-bit GTL2000,

the 2-bit GTL2002, the 8-bit GTL2003,

and the 10-bit GTL2010.

Each delivers high-speed translation

between different voltage levels with

low ON-state resistance and minimal

propagation delay.

They can translate any voltage between

1 and 5 V to any other voltage between

1 and 5 V as long as there is at least 1 V

difference between the voltage levels, so

they offer greater design flexibility than

level-shifting bus switches, which only

translate between fixed voltages.

Each GTL20xx device includes NMOS

pass transistors (Sn and Dn pins) with a
