Toshiba 3 State Octal Bus Buffer, 20-Pin TSSOP, CMOS Logic IC, 2V-5.5V Supply, 3.7ns Propagation Delay 74VHC540FT

Toshiba 74VHC540FT is an advanced high speed CMOS 3 state octal bus buffer manufactured using silicon gate C2MOS technology. It offers fast operation comparable to bipolar Schottky TTL devices while maintaining low power consumption typical of CMOS technologies. This device features an inverting logic function and is housed in a compact 20-pin TSSOP surface mount package, ideal for modern compact PCB designs.

The IC operates with a minimum supply voltage of 2V up to a maximum of 5.5V, covering a wide voltage range for versatile applications. It has a typical propagation delay time of 3.7 nanoseconds at a 5V supply with a capacitive load, allowing for high-speed data transmission. The device provides balanced propagation delays and low noise voltage levels, ensuring signal integrity in complex circuits.

The input circuitry includes protection allowing input signals from 0 to 5.5V without damage, independent of the supply voltage. When either of the control signals G1 or G2 is set high, the outputs enter a high impedance state, enabling bus sharing on multi-point lines. Power dissipation is low with a maximum supply current of 4 microamperes at room temperature.

The 74VHC540FT supports wide operating temperature ranges from -40°C to 125°C, meeting industrial and automotive standards including AEC-Q100 qualification. The device enhances communication between 5V and 3V logic systems and can be used effectively in battery backup designs or systems with dual power supplies.

Typical applications include industrial control systems, data communication buses, automotive electronics requiring reliable bus buffering, and other embedded systems requiring fast and low power buffering of digital signals.
