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. 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. TC74HC299AP TC74HC299AF Features (Note 1) (Note 2) • High speed: fmax = 42 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Outputs drive capability : 15 LSTTL loads for QA to QH 10 LSTTL loads for QA’, QH’ • • Symmetrical output impedance : |IOH| = IOL = 6 mA (min) For QA to QH |IOH| = IOL = 4 mA (min) For QA’, QH’ ∼ tpHL Balanced propagation delays: tpLH − • Wide operating voltage range: VCC (opr) = 2 to 6 V • Pin and function compatible with 74LS299 Weight DlP20-P-300-2.54A SOP20-P-300-1.27A : 1.30 g (typ.) : 0.22 g (typ.) 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 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be applied until 300 mW.
