and voltage supply extremes
I
OL
= 48mA (commercial) and 32mA (military)
CMOS power levels (1mW typ. static)
TTL input and output level compatible
CMOS output level compatible
Substantially lower input current levels than FAST
(5µA max.)
8-input universal shift register
JEDEC standard pinout for DIP and LCC
Product available in Radiation Tolerant and Radiation
Enhanced versions
Military product compliant to MIL-STD-883, Class B
Standard Military Drawing# 5962-86862 is listed on this
function. Refer to section 2.
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.
