Octal Buffers/Line Drivers with 3-STATE Outputs

General Description

The 74F240, 74F241 and 74F244 are octal buffers and line

drivers designed to be employed as memory and address

drivers, clock drivers and bus-oriented transmitters/receiv-

ers which provide improved PC and board density.

Features

s 3-STATE outputs drive bus lines or buffer memory

address registers

s Outputs sink 64 mA (48 mA mil)

s 12 mA source current

s Input clamp diodes limit high-speed termination effects
