Philips Semiconductors
Octal buffer/line driver (3-State)
Product specification
74LV541
FEATURES
• Optimized for Low Voltage applications: 1.0 to 3.6V
• Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V
• Typical VOLP (output ground bounce) t 0.8V @ VCC = 3.3V,
Tamb = 25°C
• Typical VOHV (output VOH undershoot) u 2V @ VCC = 3.3V,
Tamb = 25°C
• Non-inverting outputs
• Output capability: bus driver
• ICC category: MSI
DESCRIPTION
The 74LV541 is a low–voltage CMOS device and is pin and function
compatible with 74HC/HCT541.
The 74LV541 is an octal non-inverting buffer/line driver with 3-State
outputs. The 3-State outputs are controlled by the output enable
inputs OE1 and OE2.
A HIGH on OEn causes the outputs to assume a high impedance
OFF–state.

NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW)
PD = CPD VCC2 fi )S (CL VCC2 fo) where:
fi = input frequency in MHz; CL = output load capacity in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
S (CL VCC2 fo) = sum of the outputs.
