NC7SB3157, FSA3157 is a high performance, single-pole/double-throw (SPDT) Analog Switch or 2:1 Multiplexer/Demultiplexer Bus Switch
The NC7SB3157 and FSA3157 are high‑performance, single‑pole/double‑throw (SPDT) analog switches that can also function as 2:1 multiplexers/demultiplexers. They are fabricated in a sub‑micron CMOS process, offering fast enable/disable times, low on‑resistance, and break‑before‑make circuitry to protect signal integrity. The devices operate over a broad VCC range of 1.65 V to 5.5 V and feature rail‑to‑rail signal handling.
The datasheet provides absolute maximum ratings, DC and AC electrical characteristics, typical performance curves, packaging options (SC70 and MicroPak), and recommended land‑pattern dimensions. Ordering information includes part numbers for both standard and Pb‑free packages, supplied on tape and reel.
| Operating VCC Range | 1.65 V to 5.5 V |
|---|---|
| Control Input Overvoltage Tolerance | 7.0 V |
| Supply Voltage (Absolute Maximum) | -0.5 V to +7.0 V |
| Power Dissipation (max) | 180 mW @ +85 °C |
The device is specified to operate with a VCC between 1.65 V and 5.5 V.
It is offered in a 6‑lead SC70 (EIAJ SC88) package and a Pb‑free 6‑lead MicroPak leadless package, both supplied on tape and reel.
