General Description
The ’ACTQ827 10-bit bus buffer provides high performance
bus interface buffering for wide data/address paths or buses
carrying parity. The 10-bit buffers have NOR output enables
for maximum control flexibility. The ’ACTQ827 utilizes NSC
Quiet Series technology to guarantee quiet output switching
and improved dynamic threshold performance. FACT Quiet
Series™ feature GTO™ output control and undershoot cor-
rector in addition to a split ground bus for superior perfor-
mance.
Features
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Inputs and outputs on opposite sides of package allow
easy interface with microprocessors
n Improved latch-up immunity
n Outputs source/sink 24 mA
n Functionally and pin-compatible to AMD’s AM29827
n ’ACTQ827 has TTL-compatible inputs
n 4 kV minimum ESD immunity
n Standard Microcircuit Drawing (SMD) 5962-92199
