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
Features
Y Wide supply voltage range (3V to 15V)
Y High noise immunity (0 45 VCC typ)
Y Low power consumption
Y High capacitive load drive capability
Y TRI-STATE outputs
Y Input protection
Y TTL compatibility
Y 20-pin dual-in-line package
Y High speed 25 ns (typ ) 10V 50 pF (MM74C244)
