| TC74AC299P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC299P,TC74AC299F 8-Bit PIPO Shift Register with Asynchronousclear TC74AC299P The TC74AC299 is an advanced high speed CMOS 8-BIT PIPO SHIFT REGISTER fabricated with silicon gate and double-layer metal wiring 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 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. TC74AC299F Features (Note 1)(Note 2) * * * * High speed: fmax = 150 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 8 A (max) at Ta = 25C High noise immunity: VNIH = VNIL = 28% VCC (min) Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 * * * tansmission lines. Balanced propagation delays: tpLH tpHL - Wide operating voltage range: VCC (opr) = 2 to 5.5 V Pin and function compatible with 74F299 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.

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). Note 2: 500 mW in the range of Ta = -40 to 65C. From Ta = 65 to 85C a derating factor of -10 mW/C should be applied up to 300 mW.
