TC74VHC299FT

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. Features (Note 1) (Note 2) (Note 3) High speed: fmax = 160 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) Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 to 5.5 V Low noise: VOLP = 1.2 V (max) Pin and function compatible with 74ALS299 TC74VHC299F TC74VHC299FT 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: ...
