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 Q0 and Q7 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
specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability. No terminal voltage
may exceed Vcc by +0.5 unless otherwise noted.
