CD74HC4316数据手册TI中文资料规格书

描述 Description

The ’HC4316 and CD74HCT4316 contain four independent digitally controlled analog switches that use silicon-gate CMOS technology to achieve operating speeds similar to LSTTL with the low power consumption of standard CMOS integrated circuits.

In addition these devices contain logic-level translation circuits that provide for analog signal switching of voltages between ±5V via 5V logic. Each switch is turned on by a high-level voltage on its select input (S) when the common Enable (E) is Low. A High E disables all switches. The digital inputs can swing between VCC and GND; the analog inputs/outputs can swing between VCC as a positive limit and VEE as a negative limit. Voltage ranges are shown in Figures 2 and 3.
