TC74VHC4051AF/AFT/AFK 8-Channel Analog Multiplexer/Demultiplexer TC74VHC4052AF/AFT/AFK Dual 4-Channel Analog Multiplexer/Demultiplexer TC74V4053AF/AFT/AFK 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 signals. 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, including in the system which has two power supplies, and in battery backup circuits.

• Low ON resistance: Ron = 45Ω (typ.) (VCC = 3 V) Ron = 24Ω (typ.) (VCC = 4.5 V)
• Low power dissipation: ICC = 2.0 μA (max) (Ta = 25°C)
• Input level: VIL = 0.8V (max) (VCC = 3 V) VIH = 2.0V (min) (VCC = 3 V)
• Power down protection is provided on all control inputs
