HD74LVC16240A
16-bit Buffers / Line Drivers with 3-state Outputs
ADE-205-118B(Z)
3rd Edition
December 1996
Description
The HD74LVC16240A has sixteen inverter drivers with three state outputs in a 48 pin package. This
device is a inverting buffer and has two active low enables (1G to 4G). 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)
• All outputs VOUT (Max.) = 5.5 V (@VCC = 0 V or output off state)
• 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)
