HD74LVC16241

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

ADE-205-073B(Z)

3rd Edition

November 1995

Description

The HD74LVC16241 has sixteen buffer drivers with three state outputs in a 48 pin package. This device is
a non inverting buffer and has two active low enables (1G, 4G), high enables (2G, 3G). Each enable
independently controls four buffers. 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)
