HD74LVC16245A
16-bit Bus Transceivers with 3-state Outputs
ADE-205-120B(Z)
3rd Edition
December 1996
Description
The HD74LVC16245A has sixteen two direction buffers, for the fittest at two direction bus lines with three
state outputs. A direction control input, DIR. When DIR is high, data flows from the A inputs to the B
outputs. When DIR is high, data flows from the B inputs to the A outputs. When enable inputs (G) is high,
disables both A and B ports by placing then in a high impedance. 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)
