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
