TC74AC125P/F/FT,126P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC125P, TC74AC125F, TC74AC125FT TC74AC126P, TC74AC126F TC74AC125P/F/FT Quad Bus Buffer TC74AC126P/F Quad Bus Buffer TC74AC125P, TC74AC126P The TC74AC125/126 are advanced high speed CMOS QUAD BUS BUFFERs fabricated with silicon gate and double-layer 2 metal wiring C MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The TC74AC125 requires the 3-state control input G to be set high to place the output into the high impedance state, whereas TC74AC125F, TC74AC126F the TC74AC126 requires the control input to be set low to place the output into high impedance. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: t = 4.0 ns (typ.) at V = 5 V pd CC Low power dissipation: I = 8 A (max) at Ta = 25C CC TC74AC125FT High noise immunity: V = V = 28% V (min) NIH NIL CC Symmetrical output impedance: I = I = 24 mA (min) OH OL Capability of driving 50 transmission lines. Balanced propagation delays: t t pLH pHL Wide operating voltage range: V = 2 to 5.5 V CC (opr) Pin and function compatible with 74F125/126 Weight DIP14-P-300-2.54 : 0.96 g (typ.)
