74VHC541M – FSC

Overview

The FSC 74VHC541M is an octal buffer/line driver meticulously engineered for high-speed digital signal transmission in CMOS logic systems. Its primary function is to provide robust buffering and isolation for data buses, clock signals, and address lines, achieving propagation delays as low as 3.5 ns at VCC = 5.0 V. A critical design consideration for this device is its ability to interface between different voltage domains (e.g., 5V to 3V systems) without compromising signal integrity, thanks to its integrated input protection circuitry that tolerates 0V to 5.5V on inputs irrespective of the supply voltage, preventing damage from voltage mismatches.

Key Features

• High-speed operation: tPD = 3.5 ns (Typ) at VCC = 5.0 V
• Low static power dissipation: ICC = 4.0 µA (Max) at TA = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (Min)
• Input protection circuitry for 0V to 5.5V tolerance
• Flow-through architecture for simplified PCB layout
• Pb-Free, 20-pin TSSOP package (dimensions: 6.5mm x 4.4mm x 0.9mm)
