The Toshiba TC74ACT540P is an advanced high-speed CMOS octal bus buffer fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
This device features a propagation delay of 4.3 ns (typical) at VCC = 5 V and a low supply current of 8 µA (maximum) at 25°C. The inputs are compatible with TTL, NMOS, and CMOS output voltage levels, with VIL = 0.8 V (max) and VIH = 2.0 V (min). The symmetrical output impedance ensures |IOH| = IOL = 24 mA (min), with the capability of driving 50 Ω transmission lines.
All inputs are equipped with protection circuits against static discharge or transient excess voltage. The TC74ACT540P is available in various package types including DIP, SOP, SOL, and TSSOP, making it suitable for a wide range of applications requiring reliable bus buffering.
This octal bus buffer is pin and function compatible with 74F540/541. It can be used as a level converter for interfacing TTL or NMOS to High Speed CMOS.
