TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
8-Channel Analog Multiplexer/Demultiplexer
Dual 4-Channel Analog Multiplexer/Demultiplexer
Triple 2-Channel Analog Multiplexer/Demultiplexer
The TC74VHC4051A/4052A/4053A are high-speed, low-voltage drive
analog multiplexer/demultiplexers using silicon gate CMOS technology.
In 3 V and 5 V systems these can achieve high-speed operation with the
low power dissipation that is a feature of CMOS.
The TC74VHC4051A/4052A/4053A offer analog/digital signal selection
as well as mixed signals. The 4051A has an 8-channel configuration, the
4052A has an 4-channel × 2 configuration, and the 4053A has a 2-channel
× 3 configuration.
The switches for each channel are turned ON by the control pin digital
All control inputs are equipped with a newly developed input protection
circuit that avoids the need for a diode on the plus side (forward side from
the input to the VCC). As a result, for example, 5.5 V signals can be
permitted on the inputs even when the power supply voltage to the circuits
is off. As a result of this input power protection, the
TC74VHC4051A/4052A/4053A can be used in a variety of applications,
: 0.18 g ( typ.)
: 0.02 g ( typ.)
including in the system which has two power supplies, and in battery backup circuits.
Low ON-resistance: Ron = 45 Ω (typ.) (VCC = 3 V)
Ron = 24 Ω (typ.) (VCC = 4.5 V)
Low power dissipation: ICC = 2.0 μA (max) (Ta = 25°C)
Input level: VIL = 0.8 V (max) (VCC = 3 V)
VIH = 2.0 V (min) (VCC = 3 V)
Power down protection is provided on all control inputs
