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 undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±12mA (@VCC = 3.0 to 5.5 V) All outputs have equivalent 26 Ω series resistors, so no external resistors are required Ordering Information Part Name Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) HD74LVCR2245AFPEL HD74LVCR2245ATELL SOP–20 pin (JEITA) TSSOP–20 pin FP–20DAV TTP–20DAV FP T EL (2,000 pcs/reel) ELL (2,000 pcs/reel) Note: Please consult the sales office for the above package availability.
