This is a MM74HC4051, MM74HC4052 and MM74HC4053 8-Channel Analog Multiplexer user manual
The MM74HC4051, MM74HC4052 and MM74HC4053 are digitally controlled analog switches implemented in advanced silicon‑gate CMOS technology. They offer low on‑resistance, low leakage, and bidirectional operation, allowing control of up to ±6 V analog signals with 0‑6 V digital control.
The handbook lists features such as a wide analog input range (±6 V), typical on‑resistance of 50 Ω at 4.5 V, low quiescent current (80 µA max), and maximum output current of 25 mA per pin. Detailed pin assignments, package options, absolute maximum ratings, DC and AC electrical characteristics, and physical dimensions are provided for each device.
| Typical on‑resistance (4.5 V) | 50 Ω typ. |
|---|---|
| Low quiescent current | 80 µA max (74HC) |
| Supply voltage range (Vcc) | -0.5 V to +7.5 V |
The devices can operate with a supply voltage (Vcc) from –0.5 V up to +7.5 V.
Typical on‑resistance is 50 Ω when Voc‑Veg is 4.5 V.
They draw up to 80 µA of quiescent current (74HC version).
