DM74ALS541 Octal Buffer and Line Driver with 3-STATE Outputs
General Description
This octal buffer and line driver is designed to have the performance 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 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.

Features
s Advanced oxide-isolated ion-implanted Schottky TTL process s Switching performance is guaranteed over full temperature and VCC supply range s Data flow-thru pinout (all inputs on opposite side from outputs) s P-N-P Inputs reduce DC loading
