Description

The TC74ACT541F is an advanced high-speed CMOS octal bus buffer that falls under the product category of Buffer/Driver/Transceiver. It is manufactured using silicon gate and double-layer metal wiring C2MOS technology and achieves high-speed operation similar to Bipolar Schottky TTL while maintaining low power dissipation.

Specifications and features

The TC74ACT541F is an octal non-inverting bus buffer that is compatible with TTL, NMOS, and CMOS output voltage levels. It is equipped with protection circuits against static discharge or transient excess voltage. Features of the TC74ACT541F include:

• High-speed operation- tpd = 4.3 ns (typ.) at VCC = 5 V
• Low power dissipation- ICC = 8 µA (max) at Ta = 25°C
• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
• Balanced propagation delays: tpLH ∼ − tpHL
• Pin and function compatible with 74F540/541

Application Scenarios

The TC74ACT541F is typically used as a level converter for interfacing TTL or NMOS to High-Speed CMOS. It can also drive 50 Ω transmission lines.
