Toshiba Inverting 3 State Dual Bus Buffer 20-Pin SOIC 74HC540D

Toshiba 74HC540D is a high speed CMOS octal inverting 3 state dual bus buffer designed to enable efficient, fast switching with low power consumption in electronic circuits. This device is housed in a 20-pin SOIC surface mount package suitable for modern PCB designs.

Fabricated using silicon gate C2MOS technology, the 74HC540D combines high-speed operation comparable to LSTTL while maintaining typical CMOS low power dissipation characteristics. It supports a wide supply voltage range from 2.0 V to 6.0 V, making it versatile for various electronic applications.

The device provides inverting logic function with 3 state outputs controlled by enable pins G1 and G2, enabling buffering and bus driving in digital systems such as microprocessors and memory bus architectures. Outputs go to high impedance when either G1 or G2 inputs are high, facilitating bus sharing.

It operates reliably in harsh environments with an operating temperature range from -40°C up to 85°C. Inputs incorporate protection circuits to guard against static discharge and transient voltage spikes, enhancing device durability.

The unit exhibits balanced propagation delays with typical propagation delay time around 10 ns at 6.0 V and a maximum propagation delay of 150 ns at specified load capacitance. The device consumes a maximum supply current of 70 mA, contributing to efficient power use in embedded systems.

This 74HC540D dual bus buffer is ideal for industrial, electronic manufacturing, telecommunications, and computing equipment that requires reliable logic buffering and bus driving functionality with minimal power consumption.
