MM74C240 MM74C244
Inverting Non-Inverting Octal Buffer and
Line Driver with 3-STATE Outputs
General Description
The MM74C240 and MM74C244 octal buffers and line
drivers are monolithic complementary MOS (CMOS) inte-
grated circuits with 3-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.
