HD74LVC245A

HD74LVC245A Octal Bidirectional Transceivers with 3-state Outputs REJ03D0353–0400Z (Previous ADE-205-111B (Z)) Rev.4.00 Jul. 27, 2004 Description The HD74LVC245A has eight buffers with three state outputs in a 20 pin package. When (T / R) is high, data flows from the A inputs to the B outputs, and when (T / R) 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 = 2.0 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 ±24 mA (@VCC = 3.0 V to 5.5 V) Ordering Information ...
