It is ideal for low power and very high speed 1.8 V to 3.6 V applications; it can be interfaced to 3.6 V signal environment for both inputs and outputs. Any nG output control governs four BUS buffers. Output enable input (nG) tied together gives full 16bit operation. When nG is low, the outputs are on. When nG is high, the output are in high impedance state. This device is designed to be used with 3-state memory address drivers, etc. Bus hold on data inputs is provided in order to eliminate the need for external pull-up or pull-down resistor. The device circuits is including 26 Ω series resistance in the outputs. These resistors permit to reduce line noise in high speed applications. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage.

Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. DS3953 - Rev 11 page 6/20 3.1 Recommended conditions Table 4.
