RD74LVC245B Octal Bidirectional Transceivers with 3-state Outputs REJ03D0386–0100 Rev.1.00 Aug. 26, 2004 Description 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) • Ordering Information Part Name RD74LVC245BFPEL RD74LVC245BTELL Package Type SOP–20 pin (JEITA) TSSOP–20 pin Package Code FP–20DAV TTP–20DAV FP T Package Abbreviation Taping Abbreviation (Quantity) EL (2,000 pcs/reel) ELL (2,000 pcs/reel) • • • • • • Function Table Inputs OE L L H H: High level L: Low level X: Immaterial Z: High impedance DIR L H X Operation B data to A bus A data to B bus Z Rev.1.00 Aug. 26, 2004 page 1 of 7 RD74LVC245B Pin Arrangement DIR 1 A1 A2 2 3 20 VCC 19 OE 18 B1 17 B2 16 B3 15 B4 14 B5 13 B6 12 B7 11 B8 (Top view) A3 4 A4 5 A5 A6 A7 A8 6 7 8 9 GND 10 Absolute Maximum Ratings Item Supply voltage Input diode current Input voltage Output diode current Input / output voltage Output current VCC, GND current / pin Storage temperature Symbol VCC IIK VI IOK VI/O IO ICC or IGND Tstg –0.5 to 7.0 –50 –0.5 to 7.0 –50 50 –0.5 to VCC +0.5 –0.5 to 7.0 ±50 100 –65 to 150 mA mA °C V Ratings V mA V mA VO = –0.5 V VO = VCC +0.5 V Output "H" or "L" Output "Z" or VCC:OFF VI = –0.5 V Unit Conditions Note: The absolute maximum ratings are values, which must not individually be exceeded, and furthermore, no two of which may be realized at the same time.
