12 x 8 x 1 BiMOS-E Crosspoint Switch

The Intersil CD22M3493 is an array of 96 analog switches

capable of handling signals from DC to video. Because of

the switch structure, input signals may swing through the

total supply voltage range, VDD to VSS. Each of the 96

switches may be addressed via the ADDRESS input to the

7 to 96 line decoder. The state of the addressed switch is

established by the signal to the DATA input. A low or logic

zero input will open the switch, while a high logic level or a

one will result in closure of the addressed switch when the

STROBE input goes high from its normally low state. Any

number or combination of connections may be active at

one time. Each connection, however, must be made or

broken individually in the manner previously described. All

switches may be reset by taking the RESET input from a

zero state to a one state and then returning it to its normal

low state.
