DS1640 - Personal Computer Power FET

Description

The DS1640 contains four P channel power MOS FETs designed as switches to conserve power in personal computer systems.

Features

• Contains four P channel power FET switches that can each supply over 300 mA @ 0.2 volts drop Controlled directly from CMOS or TTL level signals Fast switching time of less than 10 µs at rated supply current 16-pin DIP or 16-pin SOIC surface mount package Positive logic signal turns each FET on and ground or low level signal turns each FET off Off condition allows less than 50 nA of current flow Low control gate capacitance of less than 5 pF FET gates can either follow inputs or be latched Design.
