DESCRIPTION

· The 74HCT4051D is an 8-channel analog multiplexer/demultiplexer.
· The 74HCT4052D is a dual 4-channel analog multiplexer/demultiplexer.
· Both devices are high-speed CMOS analog multiplexers/demultiplexers fabricated with silicon gate C2MOS technology.
· They offer high-speed operation similar to LSTTL while maintaining low power dissipation.
· Can be used as a level converter for interfacing TTL or NMOS to High-Speed CMOS.
· Inputs are compatible with TTL, NMOS, and CMOS output voltage levels.
· The control terminal's digital signal turns "ON" the corresponding switch of each channel.
· Capable of switching large amplitude signals (VCC - VEE) with small logical amplitude (VCC - GND) control signals.
· All inputs have protection circuits against static discharge or transient excess voltage.

FEATURES

· Wide operating temperature range: Topr = -40 to 125°C (for products manufactured after July 2020).
· Low power dissipation: ICC = 4.0 µA (max) at VCC = 5.5 V, VEE = GND, Ta = 25°C.
· TTL output compatibility: VIH = 2.0 V (min), VIL = 0.8 V (max).
· Wide interfacing ability: LSTTL, NMOS, CMOS.
· Low ON-resistance: RON = 50 Ω (typ.) at VCC - VEE = 9 V.
· High degree of linearity: THD = 0.020 % (typ.) at VCC - VEE = 9 V.

APPLICATIONS

· Signal routing in analog and digital systems.
· Level shifting between different logic families.
· Multiplexing and demultiplexing analog signals.
· Interface circuits for TTL, NMOS, and CMOS systems.
· Applications requiring low power consumption and high-speed operation.
