Checking for live stock

The Toshiba 74VHCT541AFT is a high-speed, single-channel (8-bit) non-inverting octal bus buffer designed for system-level digital interfaces. Operating from 4.5 V to 5.5 V, it provides 3-state outputs with TTL input compatibility and is built using VHCT silicon-gate CMOS technology to deliver TTL-speed performance with low CMOS power dissipation.

Advanced Features and Benefits of the Toshiba Octal Bus Buffer

Eight parallel non-inverting buffers (octal) for bus applications.
3-state output control (via G1/G2 inputs) supports high-speed bus sharing and tri-state signal routing.
TTL-input compatible (VIN low max = 0.8 V, VIN high min = 2.0 V) for easy integration with legacy logic.
Typical propagation delay ~5.4 ns at VCC = 5 V, enabling high-frequency digital switching.
Wide operating temperature range: –40 °C to +125 °C and built-in input/output protection up to 5.5 V for hot-insert or mixed-voltage environments.
Surface-mount 20-pin TSSOP package (6.5 × 6.4 × 1.0 mm) suited for high-density PCB designs.
RoHS-compliant and manufacturing aligned with automotive reliability standard AEC-Q100 (for applicable variants).

Engineered for Efficient Bus-Interface Performance

Designed to act as a buffer or drive interface between logic systems, the 74VHCT541AFT minimises loading on upstream sources with its high-impedance input and low-output-impedance drivers. The 3-state functionality enables multiple drivers to share a common bus line safely, making it suitable for memory interfaces, address/data buses, inter-controller communication and level-shifting tasks.

Typical Uses of the Product

Buffering address or data buses in microcontroller or FPGA systems.
Driving multiple loads or long PCB traces.
Safe bus-sharing in backplane or modular systems.
Level-shifting or interface bridging.
Embedded high-reliability designs with wide temperature or automotive grade demands.
High-density SMT PCB assemblies.
