onsemi MC74LVXT8051 Analog Multiplexers/ Demultiplexers

onsemi MC74LVXT8051 Analog Multiplexers/ Demultiplexers are high‑performance 8‑channel integrated circuits (ICs) designed using advanced silicon‑gate CMOS technology to deliver fast propagation delays, low ON‑resistance, and minimal OFF‑state leakage. Engineered for versatility, the onsemi MC74LVXT8051 components can route analog signals that span the entire supply range (from VCC to GND), suitable for a wide variety of mixed‑signal applications.

MC74LVXT8051's TTL‑compatible channel‑select and enable inputs offer seamless integration with digital control logic, while built‑in overvoltage‑tolerant input circuitry allows safe interfacing between differing logic domains, such as 3V to 5V CMOS or 1.8V to 3V CMOS, without compromising device reliability. In addition, the MC74LVXT8051 provides input protection up to 7V, supports an operating analog supply from 2.0V to 6.0V, and ensures improved linearity compared to traditional metal‑gate analog switches. The low‑noise performance, low crosstalk, and diode‑protected input/output (I/O) further enhance signal integrity, ideal for precision signal routing, measurement systems, communication interfaces, and general mixed‑signal circuit designs.
