STMicroelectronics AS11P2TLR、AS21P2TLR 模拟开关

STMicroelectronics AS11P2TLR、AS21P2TLR 是采用硅栅极 C²MOS 技术制造的高速 CMOS 低电压单/双模拟 SPDT（单刀双掷）开关或 2:1 多路复用器/解复用器。AS11P2TLR、AS21P2TLR 快速的开关时间、先断后合的延迟时间以及超低的功耗使其成为便携应用的理想选择。所有输入输出端均配备保护电路以防止静电放电，使其免于 ESD 和瞬态过压影响。

All inputs and outputs of the AS21P2TLR are equipped with protection circuits against static discharge, giving the device immunity from electrostatic discharge (ESD) and transient excess voltage.

The STMicroelectronics AS21P2TLR Analog Switch is offered in a compact 1.8mm x 1.4mm QFN10L package, ideal for space-constrained applications.
