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
