HD74LV541A

Octal Buffers / Drivers with 3-state Outputs

ADE-205-278 (Z)

1st Edition
April 1999

Description

The HD74LV541A has eight line drivers with three state outputs in a 20 pin package. When OE1 and OE2
is low level, this drivers set up output is enable. Low-voltage operation is suitable for battery-powered
products (e.g., notebook computers), and the low-power consumption extends the battery life.

Features

• VCC = 2.0 V to 5.5 V operation

• All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)

• All outputs VO (Max.) = 5.5 V (@VCC = 0 V)

• Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

• Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C)

• Output current ±8 mA (@VCC = 3.0 V to 3.6 V), ±16 mA (@VCC = 4.5 V to 5.5 V)

Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore,

no two of which may be realized at the same time.

1. The input and output voltage ratings may be exceeded if the input and output clamp-current
ratings are observed.

2. This value is limited to 5.5 V maximum.

3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
