FAST CMOS
8-INPUT UNIVERSAL
SHIFT REGISTER
DESCRIPTION:
The IDT74FCT299A is built using an advanced dual metal CMOS
technology. The IDT74FCT299A is an 8-input universal shift/storage
register 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.

NOTES:
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 +0.5V unless otherwise noted.
2. Input and Vcc terminals only.
3. Output and I/O terminals only.
