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.

Features

s Wide supply voltage range (3V to 15V)

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.
