3 Description
The SN74GTL2003 device provides eight NMOS
pass transistors (Sn and Dn) with a common gate
(G_REF) and a reference transistor (S_REF and
D_REF). 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
(S_REF/D_REF) 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.
