description
These 10-bit buffers/bus drivers provide high-
performance bus interface for wide data paths or
buses carrying parity.
The 3-state control gate is a 2-input NOR such that
if either G1 or G2 is high, all ten outputs are in the
high-impedance state.
The ′ACT11827 provides inverted data.
The 54ACT11827 is characterized for operation
over the full military temperature range of − 55°C
to 125°C. The 74ACT11827 is characterized for
operation from − 40°C to 85°C.
