74HC4051D,653

The 74HC4051D,653 is an 8-channel analog multiplexer/demultiplexer from Nexperia, part of the 74HC4051 series. It functions as a single-pole octal-throw (SP8T) switch, suitable for both analog and digital 8:1 multiplexing or demultiplexing applications. The device features three digital select inputs (S0, S1, S2), eight independent inputs/outputs (Yn), a common input/output (Z), and an enable input (E). When E is high, all switches are turned off.

Key electrical specifications include a maximum on-state resistance of 120 Ohm at VCC-VEE = 2.0 V, with typical values of 80 Ohm at 4.5 V, 70 Ohm at 6.0 V, and 60 Ohm at 9.0 V. The device offers a bandwidth of 180 MHz and fast switching times (ton 51 ns, toff 42 ns). It operates from a dual supply voltage range of ±1.5 V to ±5 V, and features low off-state leakage current (400 nA typical) and low channel capacitance (3.5 pF typical). The 74HC4051D includes ESD protection up to 2000 V HBM.

The device is packaged in a 16-pin SOIC (16-SO) surface mount package, with a body width of 3.9 mm. It is specified for operation over the full industrial temperature range of -40°C to +125°C. The 74HC4051D is compliant with RoHS3 and REACH (unverified), and has an MSL rating of 1. Applications include analog multiplexing/demultiplexing, digital multiplexing, and signal gating.
