NXP HEF4066BT 模拟开关, SPST, 4 放大器, 350 ohm, 4.5V 至 15.5V, SOIC, 14 引脚
The is a quad single-pole single-throw Analogue Switch. Each switch has two input/output terminals nY and nZ and an active high enable input nE. When nE is low, the analogue switch is turned off. The HEF4066B is pin compatible with the HEF4016B but exhibits a much lower on resistance. In addition the on resistance is relatively constant over the full input signal range.
