TC4051BF

The TC4051BF belongs to TC4051B, TC4052B and TC4053B family which are multiplexers with capabilities of selection and mixture of analog signal and digital signal. TC4051B has 8 channels configuration. TC4052B has 4 channel×2 configuration and TC4053B has 2 channel×3 configuration. The digital signal to the control terminal turns "ON" the corresponding switch of each channel, with large amplitude (VDD-VEE) can be switched by the control signal with small logical amplitude (VDD-VSS). For example, in the case of VDD=5V VSS=0V and VEE= -5V, signals between -5V and +5V can be switched from the logical circuit with single power supply of 5 volts. As the ON- resistance of each switch is low, these can be connected to the circuits with low input impedance.

The absolute maximum ratings of TC4051BF are (1)DC supply voltage VDD-VSS: -0.5~20V; (2)DC voltage VDD-VEE: -0.5~20V; (3)control input voltage VCIN: VSS-0.5~VDD+0.5V; (4)switch I/O voltage VI/VO: VEE-0.5~VDD+0.5V; (5)control input current lCIN: ±10 mA; (6)potential difference across I/O during ON VI-VO: -0.5~0.5V; (7)power dissipation PD: 300(DIP)/180 (SOIC) mW; (8)operating temperature range: -40~85°C; (9)storage temperature range: -65~150°C.

The recommended operating conditions of TC4051BF can be summarized as (1)DC supply voltage VDD-VSS/VDD-VEE: 3-18V/3-18V; (2)control input voltage VIN: VSS to VDD V; (3)input/output voltage: VEE to VDD V.
