Octal Buffers and Line Drivers with TRI-STATE

Outputs

General Description

These octal buffers and line drivers are monolithic comple-

mentary MOS (CMOS) integrated circuits with TRI-STATE

outputs These outputs have been specially designed to

drive highly capacitive loads such as bus-oriented systems

These devices have a fan out of 6 low power Schottky

loads A high logic level on the output disable control input

G makes the outputs go into the high impedance state For

improved TTL input compatibility see MM74C941
