TC74HC299AP/AF  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC74HC299AP,TC74HC299AF  
8-Bit PIPO Shift Register with Asynchronous Clear  
The TC74HC299A is a high speed CMOS 8-BIT PIPO SHIFT  
REGISTER fabricated with silicon gate C2MOS technology.  
TC74HC299AP  
It achieves the high speed operation similar to equivalent  
LSTTL while maintaining the CMOS low power dissipation.  
It has four modes (HOLD, SHIFT LEFT, SHIFT RIGHT and  
LOAD DATA) controlled by the two selection inputs (S0, S1).  
When one or both enable ( G1 , G2 ) are high, the eight I/O  
outputs are forced to the high-impedance state; however,  
sequential operation or clearing of the register is not affected.  
All inputs are equipped with protection circuits against static  
discharge or transient excess voltage.

Note 1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.  
Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull  
down resistors.
