8-Bit Bidirectional Low-voltage Translator

 

Description

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.
