Semiconductor MSC7165
16-Bit Grid Driver with 4 to 16-Decoder
This version: Nov. 1997 MSC7165 Previous version: Jul. 1996
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
* Logic supply voltage * Driver supply voltage * Driver output current : 5V : -60V
IOH : -40mA IOL : 1mA * Can be connected directly to VFD without a pull-down resistor * Built-in 4 to 16-line decoder * Brightness can be adjusted by the DUTY pin * Package: 24-pin plastic SOP (SOP24-P-430-1.27-K) (Product name: MSC7165GS-K)

PIN DESCRIPTIONS
Symbol SEL0-3 Type I 4- to 16-line decoder input pins The input 4-bit binary signals are converted into hexadecimal signals, then output through driver output pins. DUTY I Duty control signal input pin Setting this pin to "L" makes all driver outputs go "L", so this pin can be used for brightness control. GRID1-16 O 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. VDISP(-) VDD VSS -- -- -- Power supply pin for the fluorescent display tube driver circuit Logic power supply pin Ground pin Description

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).
