NC7SB3257P6X General Description

The NC7SB3257 is a high performance, 2:1 NMOS passgate multiplexer/demultiplexer. 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 seller very quickly issued and sent the order. The order exactly corresponds to the description and image on the page of orders. A small package for a month and a half was delivered to the recipient's mailbox. I'm happy with the purchase, but i still did not believe the leds. I recommend the store. I express my gratitude to the seller.
