853–0039 24025
FEATURES
High impedance NPN base inputs for reduced loading
(20
μ
A in High and Low states)
Low power, light loading
Functional pin-for-pin equivalent of 74F240
1/30th the bus loading of 74F240
Provides ideal interface and increase fan-out of MOS
microprocessors
Octal bus interface
3-State buffer outputs sink 64mA
15mA source current
DESCRIPTION
The 74F1240 is an octal buffer that is 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 device features two Output Enables, OEa
and OEb, each controlling four of the 3-State outputs.
