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.
Features
s Wide supply voltage range (3V to 15V)
s High noise immunity (0.45 VCC typ)
s Low power consumption
s High capacitive load drive capability
s 3-STATE outputs
s Input protection
s TTL compatibility
s 20-pin dual-in-line package
s High speed 25 ns (typ.) @ 10V, 50 pF (MM74C244)
Ordering Code:
Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
