TOSHIBA TC74HC4052AF(EL,F)

The TC74HC4051A/4052A/4053A are high speed CMOS ANALOG MULTIPLEXER/DEMULTIPLEXER fabricated with silicon gate C²MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC4051A has an 8 channel configuration, the TC74HC4052A has a 4 channel × 2 configuration and the TC74HC4053A has a 2 channel × 3 configuration. The digital signal to the control terminal turns “ON” the corresponding switch of each channel a large amplitude signal (VCC-VEE) can then be switched by the small logical amplitude (VCC-GND) control signal. For example, in the case of VCC = 5 V, GND = 0 V, VEE = -5 V, signals between -5 V and +5 V can be switched from the logical circuit with a single power supply of 5 V. As the ON-resistance of each switch is low, they can be connected to circuits with low input impedance. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

• High speed: tpd = 15 ns (typ.) at VCC = 5 V, VEE = 0 V
• Low power dissipation: Icc = 4 μA (max) at Ta = 25°C
• High noise immunity: ΔVNIH = VNIL = 28% VCC (min)
• Low ON resistance: RON = 50 Ω (typ.) at VCC - VEE = 9 V
• High noise immunity: THD = 0.02% (typ.) at VCC - VEE = 9 V
• Pin and function compatible with 4051/4052/4053B
