CXAS42215是一种低功耗和高可靠性的交叉点交换机。该设备包含一个8×16的交叉点开关阵列以及一个7到128线解码器和锁存电路。128个交换机中的任何一个都可以通过选择适当的7个地址位来寻址。通过对数据输入应用逻辑1或0，可以打开或关闭所选开关。VSS是数字输入的接地参考。模拟信号的范围是从VDD到VEE。芯片选择（CS）允许交叉点阵列级联以进行矩阵扩展
•内部控制锁存器和地址解码器
•设置和保持时间短
•宽工作电压：4.5V至13.2V
•12VPP模拟信号能力
•在VDD=12V，TA=+25℃时，RON=40Ω（典型值）
•在VDD=12V，TA=+25℃时，ΔRON=3Ω（典型值）
•全CMOS开关，低失真
•最小馈通和串扰
•单独的模拟和数字参考电源
•低功耗

产品概述 返回TOP
The CXAS42215 is a low power dissipation and high reliability crosspoint switch. The device contains an 8×16 array of crosspoint switches along with a 7 to 128 line decoder and latch circuits. Any one of the 128 switches can be addressed by selecting the appropriate seven address bits. The selected switch can be turned on or off by applying a logical one or zero to the DATA input. VSS is the ground reference of the digital inputs. The range of the analog signal is from VDD to VEE. Chip Select (CS) allows the crosspoint array to be cascaded for matrix expansion.
The CXAS42215 is available in Green LQFP-10×10-44L and PLCC-44L packages. It operates over an ambient temperature range of -40℃ to +85℃.
