TC74ACT299P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT299P, TC74ACT299F 8-Bit PIPO Shift Register with Asynchronous Clear The TC74ACT299 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. This device may be used as a level converter for interfacing TLL or NMOS to High Speed CMOS. The inputs are patible with TTL, NMOS and CMOS output voltage levels. 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. TC74ACT299P TC74ACT299F Features (Note 1)(Note 2) - High speed: fmax = 130 MHz (typ.) at VCC = 5 V - Low power dissipation: ICC = 8 μA (max) at Ta = 25°C - patible with TTL outputs: VIL = 0.8 V (max) VIH = 2.0 V (min) - Symmetrical output impedance: |IOH| = IOL = 24 m A (min) Capability of driving 50 Ω transmission lines. - Balanced propagation delays: tp LH ∼- tp HL - Pin and function patible with 74F299 Weight DIP20-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.
