Octal Inverting Buffer and Line Driver
with 3-STATE Outputs
General Description
This octal buffer and line driver is designed to have the per-
formance of the DM74ALS240A series and, at the same
time, offer a pinout with inputs and outputs on opposite
sides of the package. This arrangement greatly enhances
printed circuit board layout. The 3-STATE control gate is a
2-input NOR such that if either G1 or G2 is HIGH, all eight
outputs are in the high impedance state.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
