DM74ALS541
Octal 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
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

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.
