TC74HC125AP/AF,126AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC125AP, TC74HC125AF TC74HC126AP, TC74HC126AF TC74HC125AP/AF Quad Bus Buffer TC74HC126AP/AF Quad Bus Buffer TC74HC125AP, TC74HC126AP The TC74HC125A/126A are high speed CMOS QUAD BUS 2 BUFFERs fabricated with silicon gate C MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC125A requires the 3-state control input G to be set high to place the output into the high impedance state, whereas the TC74HC126A requires the control input to be set low to place the output into high impedance. TC74HC125AF, TC74HC126AF All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: t = 10 ns (typ.) at V = 5 V pd CC Low power dissipation: I = 4 A (max) at Ta = 25C CC High noise immunity: V = V = 28% V (min) NIH NIL CC Output drive capability: 15 LSTTL loads Symmetrical output impedance: I = I = 6 mA (min) OH OL Balanced propagation delays: t t pLH pHL Weight DIP14-P-300-2.54 : 0.96 g (typ.) Wide operating voltage range: V (opr) = 2 to 6 V CC SOP14-P-300-1.27A : 0.18 g (typ.)
