TC74HC299AP Overview
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;.
TC74HC299AP Key Features
- 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
- Symmetrical output impedance : |IOH| = IOL = 6 mA (min) For QA to QH |IOH| = IOL = 4 mA (min) For QA’, QH’
- Balanced propagation delays: tpLH ∼- tpHL
- Wide operating voltage range: VCC (opr) = 2 to 6 V
- Pin and function patible with 74LS299
