1 / 5 page © 2000 Fairchild Semiconductor Corporation DS009170 www.fairchildsemi.com October 1986 Revised February 2000 DM74ALS540A 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. Features s Advanced oxide-isolated, ion-implanted Schottky TTL process s Switching performance is guaranteed over full tempera- ture and VCC supply range s Data flow-thru pinout (All inputs on opposite side from outputs) s P-N-P inputs reduce DC loading Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
