1. Other frequencies may be available, please contact factory with your special requirements.
2. A 0.1 µF low frequency tantalum bypass capacitor in parallel with a 0.01 µF high frequency ceramic capacitor is recommended. Both should be located as close to the FTU-Type bias pin as is practical
3. Figure 1 defines these parameters. Figure 2 illustrates the equivalent TTL load and operating conditions under which these parameters are specified and tested.

Handling Precautions
Although protection circuitry has been designed into this
device, proper precautions should be taken to avoid exposure
to electrostatic discharge (ESD) during handling and mounting.
VTI employs a human-body model (HBM) and a chargeddevice model (CDM) for ESD-susceptibility testing and
protection design evaluation.

ESD voltage thresholds are dependent on the circuit
parameters used to define the mode. Although no industrywide standard has been adopted for the CDM, a standard HBM
(resistance = 1500Ω, capacitance = 100pF) is widely used and
therefore can be used for comparison purposes. The HBM
ESD threshold presented here was obtained by using these
circuit parameters.
