The M54/74HC4316 is a high speed CMOS QUAD BILATERAL SWITCH fabricated in silicon gate C2MOS technology. It has high speed performance combined with true CMOS low power consumption. HC4316 has four independent analogue switches. Each switch has two input/output terminals (nI/O, nO/I and an active high select input (nC). When the enable input is high all four analog switches are off. The supply voltage for the digital signals applied to VCC and GND must be within the range 0 to 6 V. The voltage swing on the analogue Input/Outputs can be between VCC (Positive Limit) and VEE (Negative Limit). The voltage between VCC and VEE must not exceed 12 V.
