The NC7SB3257 is a high performance, 2:1 NMOS passgate multiplexer/demultiplexer from Fairchild Semiconductor Corporation. The device is fabricated with advanced sub-micron CMOS technology to achieve high speed enable and disable times and low On Resistance. The device is specified to operate over the 4.0 to 5.5V VCC operating range. The control input tolerates voltages up to 5.5V independent of the VCC operating range.
The NC7SB3257 is a 2:1 NMOS pass‑gate multiplexer/demultiplexer fabricated in sub‑micron CMOS technology. It operates over a 4.0 V to 5.5 V supply range and features a TTL‑compatible control input with over‑voltage tolerance up to 7 V.
Key features include a space‑saving SC70 6‑lead package, an ultra‑small MicroPak™ leadless package, low on‑resistance (typical 3 Ω at 5 V), fast propagation delay (≈0.25 ns), and break‑before‑make enable circuitry. Electrical characteristics, pin assignments, and packaging details are provided for design integration.
