DESCRIPTION

The 74ACT299 is an advanced high-speed CMOS

8-BIT PIPO

SHIFT REGISTER (3-STATE)

fabricated with sub-micron silicon gate and

double-layer metal wiring C

MOS technology.

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

PIN CONNECTION AND IEC LOGIC SYMBOLS

-O

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

asynchronousto 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.
