DESCRIPTION
The ACT299 is an high-speed CMOS 8-BIT PIPO
SHIFT REGISTERS (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C

MOS technology. It is ideal for low
power
applications
mantaining
operation similar to equivalent Bipolar Schottky
TTL.
high
speed
These devices have four modes (HOLD, SHIFT
LEFT, SHIFT RIGHT and LOAD DATA). Each
mode is chosen by two functionselect inputs (S0,
S1)as shownin the TruthTable.
When one or both enable inputs, (G1, G2) are
high, the eight input/output terminals are in
the high-impedance state ; however sequential
operation or clearing of the register is not
affected.Clear function is synchronousto clock.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
