TC74ACT273P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT273P, TC74ACT273F Octal D-Type Flip Flop with Clear TC74ACT273P The TC74ACT273 is an advanced high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate and 2 double-layer metal wiring C MOS 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 TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. TC74ACT273F Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the clock pulse. When the CLR input is held L, the Q outputs are at a low logic level independent of the other inputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: f = 170 MHz (typ.) at V = 5 V max CC Weight Low power dissipation: I = 8 A (max) at Ta = 25C CC DIP20-P-300-2.54A : 1.30 g (typ.) SOP20-P-300-1.27A : 0.22 g (typ.) Compatible with TTL outputs: V = 0.8 V (max) IL V = 2.0 V (min) IH Symmetrical output impedance: I = I = 24 mA (min) OH OL Capability of driving 50 transmission lines. Balanced propagation delays: t t pLH pHL Pin and function compatible with 74F273 Pin Assignment Start of commercial production 1989-05 1 2014-03-01 TC74ACT273P/F IEC Logic Symbol Truth Table Inputs Output Function CLR D CK Q L X X L Clear H L L H H H H X Qn No Change X: Dont care System Diagram 2 2014-03-01
