HD74LVCR2245A

HD74LVCR2245A Octal Bidirectional Transceivers with 3–state Outputs REJ03D0377–0400 (Previous ADE-205-235B (Z)) Rev.4.00 Aug. 20, 2004 Description The HD74LVCR2245A 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. All outputs, which are designed to sink up to 12mA, include equivalent 26 Ω resistors to reduce overshoot and undershoot. Low voltage and high-speed operation is suitable at 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 to 5.5 V All inputs VIH (Max) = 5.5 V (@VCC = 0 to 5.5 V) All inputs / 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 und...
