The MADR-011021 four channel switch driver is
designed to work with MACOM’s Series/Shunt SP4T
PIN diode switches (e.g., MASW-011077). This
driver has 1 series output and 1 shunt output per
channel which can provide up to 600 mA sinking
(series), 100 mA sinking (shunt), and 5 mA sourcing
bias current.

The bias voltage can be selected to be any voltage
between 10 V to 180 V. This switch driver can be
easily controlled by standard TTL logic. With low
quiescent current of <0.4 mA, this driver has a
typical delay of <5 µs when driving a 1200 pF
capacitive load.
