RD74LVC245B
Octal Bidirectional Transceivers with 3-state Outputs
Description
REJ03D0386â0100
Rev.1.00
Aug. 26, 2004
The RD74LVC245B has eight buffers with three state outputs in a 20 pin package. When (DIR) is high, data flows
from the A inputs to the B outputs, and when (DIR) is low, data flows from the B inputs to the A outputs. A and B bus
are separated by making enable input (OE) high level. 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 input outputs VI/O (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)
