ON Semiconductor 74VHCT541AMTC Octal Buffer/Line Driver

The 74VHCT541AMTC is a high-speed CMOS octal buffer/line driver designed by ON Semiconductor to provide interface buffering between two buses. With its advanced silicon-gate CMOS technology, it offers the high-speed operation of LSTTL combined with the power-saving features of CMOS technology. This device is ideal for driving bus lines or buffer memory address registers with its balanced drive and high current capability.

Featuring eight non-inverting buffers with 3-state outputs, the 74VHCT541AMTC is capable of driving heavily loaded buses with the least amount of cross-talk. Each output can sink 25 mA and source 20 mA, making this component suitable for interfacing with high-drive components. The 3-state control gate is a common feature that allows for the output to be placed in a high-impedance state, effectively disconnecting the output from the bus, which is beneficial in preventing bus contention.

The device is housed in a compact 20-pin TSSOP package, making it suitable for space-constrained applications. It operates over a broad voltage range of 4.5V to 5.5V and offers a spec-compliant performance for 5V systems. The 74VHCT541AMTC is characterized for operation from -55°C to +125°C, ensuring reliable performance across a wide range of environmental conditions.

Key features of the 74VHCT541AMTC include:

• High-speed: t<sub>PD = 5.2 ns (typ) at V<sub>CC = 5V
• Low power dissipation: I<sub>CC = 4 μA (max) at T<sub>A = 25°C
• High noise immunity: V<sub>NIH = V<sub>NIL = 28% V<sub>CC (min)
• Power-down protection provided on inputs and outputs
• Pin and function compatible with 74 series logic

With its robust design and high functionality, the 74VHCT541AMTC from ON Semiconductor is an excellent choice for applications requiring high-speed data transfer and buffering, such as computers, servers, and telecommunications systems. Its industry-standard footprint ensures easy integration into various designs without the need for significant board modifications.
