HD74LVC16541

16-bit Buffers / Line Drivers with 3-state Outputs

ADE-205-058B(Z)

Rev.2

September 1995

Description

The HD74LVC16541 has sixteen buffers with three state outputs in a 48 pin package. When G1 and G 2 is
low level, this drivers set up output is enable. Low voltage and high speed operation is suitable at the
battery drive product (note type personal computer) and low power consumption extends the life of a
battery for long time operation.

Features

• VCC = 2.0 V to 5.5 V

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

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

• Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)

• High output current ±24 mA (@VCC = 3.0 V to 5.5 V)
