TC74VHC299F/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC299F,TC74VHC299FT
8-Bit Pipo Shift Register with Asynchronous Clear
The TC74VHC299 is an advanced high speed CMOS 8-BIT PIPO SHIFT REGISTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It has a 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 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.

Weight SOP20-P-300-1.27A TSSOP20-P-0044-0.65A
: 0.22 g (typ.) : 0.08 g (typ.)
Note 1: Do not apply a signal to A/QA to H/QH bus terminal when it is in the output mode. Damage may result. Note 2: All floating (high impedance) A/QA to H/QH bus terminals must have their input levels fixed by means of pull up or pull down resistors. Note 3: A parasitic diode is formed between A/QA to H/QH bus and VCC terminals. Therefore bus terminal can not be used to interface 5 V to 3 V systems directly.

Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
