RD74LVC16245B
16-bit Bus Transceivers with 3-state Outputs
Description
REJ03D0529–0100
Rev.1.00
Apr. 18, 2005
The RD74LVC16245B 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 low, 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 = 1.65 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 ±4 mA (@VCC = 1.65 V)
±8 mA (@VCC = 2.3 V)
±12 mA (@VCC = 2.7 V)
±24 mA (@VCC = 3.0 V to 5.5 V)
