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.
