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

2MOS technology. It is ideal for low

power

applications

mantaining

high

speed

operation similar to equivalent Bipolar Schottky

TTL.

These devices have four modes (HOLD, SHIFT

LEFT, SHIFT RIGHT and LOAD DATA). Each

mode is chosen by two function select inputs (S0,

S1) as shown in the Truth Table.

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 synchronous to 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

equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
