MSC7165
16-Bit Grid Driver with 4 to 16-Decoder
GENERAL DESCRIPTION
The MSC7165 is a driver IC designed to directly drive the grids of a vacuum fluorescent display
tube.
Since this IC has a built-in 4 to 16-line decoder and 16 output circuits, a single device of MSC7165
can replace a set of the following three: two devices of either MSL915 or MSL917 and one device
of either MSM4514 or MSM74HC4514.
Setting the DUTY pin to the "L" level makes all driver outputs go "L". Blanking can be set using
this function.
FEATURES

I
The input 4-bit binary signals are converted into hexadecimal signals, then output
through driver output pins.
Duty control signal input pin
DUTY
Setting this pin to "L" makes all driver outputs go "L", so this pin can be used for
brightness control.
High withstand voltage driver output pins for driving fluorescent display tube
These pins can be connected directly to the grid of fluorescent display tube.
No pull-down resistor is required.

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the
product name, package name, pin number, package code and desired mounting conditions
(reflow method, temperature and times).
