DESCRIPTION:
The IDT54/74FCT299 and IDT54/74FCT299A/C are built
using an advanced dual metal CMOS technology. The IDT54/
74FCT299 and IDT54/74FCT299A/C are 8-input universal
shift/storage registers with 3-state outputs. Four modes of
operation are possible: hold (store), shift left, shift right and
load data. The parallel load inputs and flip-flop outputs are
multiplexed to reduce the total number of package pins.
Additional outputs are provided for flip-flops Q
0
and Q
7
to
allow easy serial cascading. A separate active LOW Master
Reset is used to reset the register.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
