MM54C240 MM74C240 Inverting MM54C244 MM74C244 Non-Inverting Octal Buffers and Line Drivers with TRI-STATE Outputs
General Description
These octal buffers and line drivers are monolithic complementary 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)
