DS3649 - Hex TRI-STATE TTLto MOS Drivers

This page provides the datasheet information for the DS3649, a member of the DS3649J Hex TRI-STATE TTLto MOS Drivers family.

Description

The DS1649 DS3649 and DS1679 DS3679 are Hex TRI-STATE MOS drivers with outputs designed to drive large capacitive loads up to 500 pF associated with MOS memory systems PNP input transistors are employed to reduce input currents allowing the large fan-out to these drivers needed in memory systems The

Features

  • Y High speed capabilities  Typ 9 ns driving 50 pF  Typ 30 ns driving 500 pF Y TRI-STATE outputs for data bussing Y Built-in 15X dam.
