Octal 3-STATE Bus Driver
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 communication systems.
The output 3-STATE gating control is organized into two
separate groups of four buffers. The DM74ALS240A con-
trol inputs symmetrically enable the respective outputs
when set logic LOW, while the DM74ALS241A has comple-
mentary 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 eliminates bus glitching problems that arise
during power-up and power-down.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
