TC74HC374APF Toshiba

TC74HC374AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC374AP, TC74HC374AF Octal D-Type Flip-Flop with 3-State Output The TC74HC374A is a high speed CMOS OCTAL FLIP-FLOP 2 TC74HC374AP with 3-STATE OUTPUT fabricated with silicon gate C MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. These 8-bit D-type flip-flops are controlled by a clock input (CK) and an output enable input ( OE ). When the OE input is high, the eight outputs are in a high impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltage. TC74HC374AF Features High speed: f = 77 MHz (typ.) at V = 5 V max 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 Wide operating voltage range: V (opr) = 2 to 6 V CC DIP20-P-300-2.54A : 1.30 g (typ.)
