FEATURES
High impedance NPN base inputs for reduced loading
(20
A in High and Low states)
Low power, light bus loading
Functionally similar to the 74F240 and 74F241
Provides ideal interface and increases fan-out of MOS
microprocessors
Efficient pinout to facilitate PC board layout
Octal bus interface
3-State buffer outputs sink 64mA
15mA source current
DESCRIPTION
The 74F540 and 74F541 are octal buffers that are ideal for driving
bus lines or buffer memory address registers. The outputs are
capable of sinking 64mA and sourcing up to 15mA, producing very
good capacitive drive characteristics. The devices feature input and
outputs on opposite sides of the package to facilitate printed circuit
board layout.

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value under the recommended operating conditions for the applicable type.
2. All typical values are at V
CC
= 5V, T
amb
= 25
C.
3. Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
should be performed last.
