GTLP1B151 Features
Separate LVTTL inputs and outputs
A feedback path for control and diagnostics monitoring
Bidirectional interface between GTLP and LVTTL logiclevels
Designed with edge rate control circuitry to reduce out-put noise on the GTLP port
VREF pin provides external supply reference voltage forreceiver threshold adjustibility
Special PVT compensation circuitry to provide consis-
tent performance over variations of process, supply volt-age 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 liveinsertion
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
