The SN74GTL2003 device provides eight NMOS pass transistors (Sn and Dn) with a common
gate (GREF) and a reference transistor (SREF and
DREF). The low ON-state resistance of the switch allows connections to be
made with minimal propagation delay. With no direction control pin required, the device allows
bidirectional voltage translations any voltage (0.95 V to 5 V) to any voltage (0.95 V to 5 V).
All transistors in the SN74GTL2003 have the same electrical characteristics, and there
is minimal deviation from one output to another in voltage or propagation delay. This offers
superior matching over discrete transistor voltage-translation solutions where the fabrication of
the transistors is not symmetrical. With all transistors being identical, the reference transistor
(SREF/DREF) can be located on any of the other eight
matched Sn/Dn transistors, allowing for easier board layout. The translator transistors with
integrated ESD circuitry provides excellent ESD protection.
