TC74ACT541P

The Toshiba TC74ACT541P is an advanced high-speed CMOS octal bus buffer featuring non-inverting, 3-state outputs. Fabricated with silicon gate and double-layer metal wiring C2MOS technology, it achieves high-speed operation comparable to bipolar Schottky TTL while maintaining low CMOS power dissipation.

This device is suitable for level conversion between TTL or NMOS and High-Speed CMOS. Its inputs are compatible with TTL, NMOS, and CMOS output voltage levels. The outputs enter a high-impedance state when either of the 1G or 2G enable inputs are high. All inputs are protected against static discharge or transient excess voltage.

Key electrical characteristics include a typical propagation delay of 4.3 ns at 5V VCC and a maximum supply current of 8 µA at 25°C. It supports TTL output compatibility with a maximum VIL of 0.8V and a minimum VIH of 2.0V. The symmetrical output impedance allows for a minimum |IOH| and IOL of 24 mA, with the capability of driving 50 Ω transmission lines.

The TC74ACT541P is pin and function compatible with 74F540/541. Available package weights include DIP20 (1.30 g typ.), SOP20 (0.22 g typ.), SOL20 (0.46 g typ.), and TSSOP20 (0.08 g typ.).
