General Description
The GTLP1B151 is a 1-bit transceiver that provides LVTTL-to-GTLP signal level translation. Individual LVTTL and GTLP driver enables are also available. The GTLP1B151 offers separate LVTTL inputs and outputs, and can provide a feedback path for control and diagnostics monitoring.

Features
■ Separate LVTTL inputs and outputs
■ A feedback path for control and diagnostics monitoring
■ Bidirectional interface between GTLP and LVTTL logic levels
■ Designed with edge rate control circuitry to reduce output noise on the GTLP port
■ VREF pin provides external supply reference voltage for receiver threshold adjustibility
■ Special PVT compensation circuitry to provide consistent performance over variations of process, supply voltage and temperature
■ 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 live insertion
■ Open drain on GTLP to support wired-or connection
■ Flow through pinout optimizes PCB layout
■ A Port source/sink −24mA / +24mA
■ B Port sink +50mA
