16-bit Buffers / Line Drivers with 3-state Outputs
ADE-205-057B(Z)
Rev.2
September 1995
Description
The HD74LVC16540 has sixteen inverter drivers 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
• V_CC = 2.0 V to 5.5 V
• All inputs V_IH (Max.) = 5.5 V (@V_CC = 0 V to 5.5 V)
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.0 V (@V_CC = 3.3 V, Ta = 25°C)
• High output current ±24 mA (@V_CC = 3.0 V to 5.5 V)
