DM74ALS540A Octal Inverting Buffer and Line Driver with 3-STATE Outputs

DM74ALS540A Octal Inverting Buffer and Line Driver with 3-STATE Outputs

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 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.
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

Note 1 The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation.
