TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7W53F,TC7W53FU,TC7W53FK
2-Channel Multiplexer/Demultiplexer
The TC7W53 is a high speed CMOS Analog Multiplexer/
Demultiplexer fabricated with silicon gate CMOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC7W53 has a 2 channel 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 signal power supply of 5 V. As the ON-resistance of
each switch is low, they can be connected to circuit with low input
impedance.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
High speed: tpd = 15 ns (typ.) at VCC = 5 V, VEE = 0 V
Low power dissipation: ICC = 1 μA (max) at Ta = 25°C
High noise immunity: VNIH = VNIL = 28% VCC (min)
Low ON resistance: RON = 50 Ω (typ.) at VCC – VEE = 9 V
High degree of linearity: THD = 0.02 (typ.) at VCC – VEE = 9 V
Pin and function compatible with TC4W53
