HEX-Reg
TM
5.1 Volt Zener Diode Array
for Hex Attenuator Drivers
SCOTTSDALE DIVISION
DESCRIPTION
The SM16Z4689 is designed for supplying the 5 volt bias at 50
μA
for hex attenuator driver components. These provide the
controlling voltage for 6-bit digital GaAs attenuators such as the
Hittite HMC424LP3. This low current, 50
μA
5.1V zener array
provides the necessary bias for the High State, 4.2 – 5.0 V,
conditions when it triggers the associated driver. The HEX-
Reg
TM
voltage regulator array is supplied in the SO-16 package
with two spare diodes for applications requiring up to eight
diodes. A suggested driver circuit in figure 1 illustrates one of
the six inputs to a 6-bit attenuator.

APPLICATIONS
The HEX-Reg
TM
Zener diode array is designed to mount adjacent to a 6-line driver with one of
the driver circuits shown below. The 5.1 volt, low-current Zener assures correct bias for the
low state and high state of the driven attenuator. Diodes are fully isolated and internally
arranged for optimum circuit layout.
