Overview

The Intersil CD22M3494 is an array of 128 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 VEE. Each of the 128 switches may be addressed via the ADDRESS input to the 7 to 128 line decoder. The state of the addressed switch is established by the signal to the DATA input. A low or 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. CS allows crosspoint array to be cascaded for matrix expansion.

  1. What is the difference between CD22M3494MQZ and CD22M3494MQAZ?

    Question:1. What is the difference between CD22M3494MQZ and CD22M3494MQAZ? 2. What does 'A' Suffix mean?   Answer:The  'A' suffix was generated to denote the modified CD22M3494 which had the improved latch-up spec. The change was incorporated into the non "A" parts in 9-27-1993. Since we had ...
