Toshiba 3 State Octal Bus Buffer 20-Pin TSSOP 4.5-5.5V CMOS Logic IC 74VHCT541AFT

Toshiba 74VHCT541AFT is a 3 state octal bus buffer logic IC designed with advanced high speed CMOS C2MOS technology. It provides the high speed operation similar to Bipolar Schottky TTL devices while maintaining low power dissipation characteristic of CMOS devices. The device is housed in a compact 20-pin TSSOP surface mount package measuring 6.5mm in length and 1mm in height, making it suitable for dense PCB layouts.

It features 3-state outputs, allowing for effective bus interfacing. The input voltage levels are compatible with TTL outputs, enabling easy integration in mixed logic level systems. Additionally, the device supports level shifting from 3.3V to 5V systems.

With an operating temperature range from -40°C to 125°C and automotive standard qualification AEC-Q100, the 74VHCT541AFT is suitable for industrial, automotive, and other demanding environments. Low supply current of 4μA and propagation delay of typically 5.4ns contribute to efficient and fast signal buffering.

Additional technical features include power down protection on all inputs and outputs, low noise with maximum VOLP of 1.0V, and balanced propagation delays (tPLH approximately equals tPHL). The device maintains high reliability in applications requiring stable and fast logic buffering.

Advanced silicon gate C2MOS technology ensures high speed and low power. Compatible with TTL inputs with proper input voltage thresholds. Wide temperature range supports industrial and automotive use. 3-state outputs ideal for bus buffer applications.

Compact 20-pin TSSOP package fits modern surface mount designs. Low supply current minimizes energy consumption. Automotive AEC-Q100 standard qualified for enhanced reliability. Balanced and low propagation delays enable precise timing.

Power down protection prevents damage due to mismatched voltages. Supports level shifting and memory driver applications.

This logic IC is used widely in electronics, power & connectors, semiconductor, and buffer applications across industrial and automotive sectors. For development, compatible designs with 3-state memory drivers and level conversion systems benefit from this device. Explore related buffer ICs and logic components in EnvMart.
