The low ON-state resistance of the switch to 5 V allows connections to be made with minimal propagation delay. With no direction control pin • Provides Direct Interface With GTL, GTL+, required, the device allows bidirectional voltage LVTTL/TTL, and 5-V CMOS Levels translations any voltage (0.95 V to 5 V) to any • Low ON-State Resistance Between Input and voltage (0.95 V to 5 V). Output Pins (Sn/Dn) All transistors in the SN74GTL2003 have the • Supports Hot Insertion same electrical characteristics, and there is • No Power Supply Required – Will Not Latch Up minimal deviation from one output to another in voltage or propagation delay. This offers superior • 5-V-Tolerant Inputs matching over discrete transistor voltage- • Low Standby Current translation solutions where the fabrication of the • Flow-Through Pinout for Ease of Printed Circuit transistors is not symmetrical. With all transistors Board Trace Routing being identical, the reference transistor (SREF/DREF) can be located on any of the other 2 Applications eight matched Sn/Dn transistors, allowing for easier board layout. The translator transistors • Bidirectional or Unidirectional Applications with integrated ESD circuitry provides excellent Requiring Voltage-Level Translation From Any ESD protection.
