TC7MBL3253CFK(EL)

Overview

The TC7MBL3253CFK is a low-voltage, low-capacitance CMOS dual 1-of-4 multiplexer/demultiplexer. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. The device features two independent multiplexers with common select inputs (S1, S0) and output enable (OE). Key electrical characteristics include a typical ON-resistance of 9 Ω at 3.0 V and a typical ON capacitance of 13 pF. Propagation delays are specified up to 11 ns depending on the supply voltage.

Feature Summary
