NC7SB3257 TinyLogic

General Description

The NC7SB3257 is a high performance, 2:1 NMOS pass- gate multiplexer/demultiplexer from Fairchild’s Ultra High Speed Series of TinyLogic . 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.

Features

■Space saving SC70 6-lead surface mount package

■Ultra small MicroPak leadless package

■Typical 3Ω switch resistance @ 5.0V VCC

■Minimal propagation delay through the switch

■Power down high impedance control input

■Zero bounce in flow through mode

■TTL compatible control input

■Overvoltage tolerance of control input to 7.0V

■Break before make enable circuitry
