General Description
The GTLP10B320 is a 10-bit Universal bus driver and receiver, with separate LVTTL inputs and outputs and a feedback path for diagnostics, that provides LVTTL to GTLP signal level translation. High speed backplane operation is a direct result of GTLP’s reduced output swing (<1V), reduced input threshold levels and output edge rate control. The edge rate control minimizes bus settling time. GTLP is a Fairchild Semiconductor derivative of the Gunning Transistor logic (GTL) JEDEC standard JESD8-3.

Features
■ Bidirectional interface between GTLP and LVTTL logic levels
■ Variable edge rate control pin to select desired edge rate on GTLP port (VERC)
■ VREF pin provides external supply reference voltage for receiver threshold adjustibility
■ Split LVTTL inputs and outputs
■ Special PVT compensation circuitry to provide consistent performance over variations of process, supply voltage and temperature
■ A feedback path for control and diagnostics monitoring
■ TTL compatible driver and control inputs
■ Designed using Fairchild advanced BiCMOS technology
■ Bushold data inputs on A port to eliminate the need for external pull-up resistors for unused inputs
■ Power up/down and power off high impedance for liveinsertion
■ Open drain on GTLP to support wired-or connection
■ Flow through pinout optimizes PCB layout
■ A Port source/sink −24mA/+24mA
