8 CROSSPOINT SWITCH
WITH CONTROL MEMORY
Description
The GM62093A contains a 12
8 array of
crosspoint together with a 7 to 96 Line decoder
and latch circuits. The GM62093A employs
LG's advanced high voltage CMOS process
technology. It provides extra low operating
current and low power dissipation.
Anyone of the 96 switchs can be addressed by
selecting the ap-propriate 7 input bits. The
selected turned on or off by applying a logical
one or zero to the data in and the strobe input
at logical one. A reset signal can be used to
turn off all the switches together when is
switched at logical one. The GM62093A is
avail-able in a 40 lead dual in-line plastic and
ceramic package.

Functional Description

The GM62093A contains a 12
8 array of
analog switches, each with a latch to maintain
its on(closed)or off(opened) state.
Seven ADDRESS lines(AX0~AX3,
AY0~AY2) are provided to address any one of
the 96 switches.
After any one of the switches is selected, the
DATA pin may be held high to turn the switch
on, or low to turn it off.
Finally a positive pulse to the STROBE pin
initiates the ac-tion determined by the
ADDRESS and DATA pins. All 96 switches
can be turned off by forcing the RESET pin
high.
