General Description
These octal 3-STATE bus drivers are designed to
provide the designer with flexibility in implementing a bus
interface with memory, microprocessor, or communi-
cation systems. The output 3-STATE gating control is
organized into two separate groups of four buffers.
The DM74ALS240A control inputs symmetrically enable
the respective outputs when set logic LOW, while the
DM74ALS241A has complementary enable gating.
The 3-STATE circuitry contains a feature that maintains
the buffer outputs in 3-STATE (high impedance state)
during power supply ramp-up or ramp-down. This elimi-
nates bus glitching problems that arise during power-up
and power-down.
Schottky TTL process
Functional and pin compatible with the DM74LS
counterpart
Improved switching performance with less power
dissipation compared with the DM74LS counterpart
Switching response specified into 500
and 50pF
load
Switching response specifications guaranteed over
full temperature and V
CC
supply range
PNP input design reduces input loading
