TC74ACT374P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT374P, TC74ACT374F, TC74ACT374FT Octal D-Type Flip-Flop with 3-State Output The TC74ACT374 is an advanced high speed CMOS OCTAL FLIP-FLOP fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This devices 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. These 8-bit D-type flip-flops are controlled by a clock input (CK) and a 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. Features • High speed: fmax = 180 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 8 μA (max) at Ta = 25°C • Compatible with TTL outputs: VIL = 0.8 V (max) VIH = 2.0 V (min) • Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω transmission lines. • Balanced propagation delays: tpLH ∼− tpHL • Pin and function compatible with 74F374 TC74ACT374P TC74ACT374F TC74ACT374FT Weight DIP20-P-300-2.54A SOP20-P-300-1.27A TSSOP20-P-0044-0.65A : 1.30 g (typ.) : 0.22 g (typ.) : 0.08 g (typ.)
