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.
- 45O (Typ)…VCC = 4.5V
- 35O (Typ)…VCC = 6V
- 30O (Typ)…VCC – VEE = 9V
- 2V to 10V Operation
- High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
- Direct LSTTL Input Logic Compatibility, VIL = 0.8V (Max), VIH = 2V (Min)
- CMOS Input Compatibility, Il = 1µA at VOL, VOH
