RD74LVC125B Quad. Bus Buffer Gates with 3-state Outputs REJ03D0498–0200 Rev.2.00 Dec. 10, 2004 Description The RD74LVC125B has four bus buffer gates in a 14 pin package. The device requires the three state control input OE to be taken high to put the output into the high impedance condition. 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 outputs VOUT (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 Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) RD74LVC125BFPEL SOP–14 pin (JEITA) FP–14DAV FP EL (2,000 pcs/reel) RD74LVC125BTELL TSSOP–14 pin TTP–14DV T ELL (2,000 pcs/reel) Function Table Inputs OE Outputs Y A H X Z L L L H H L H: High level L: Low level X: Immaterial Z: High impedance Rev.2.00 Dec. 10, 2004 page 1 of 8 RD74LVC125B Pin Arrangement 1OE 1 14 V CC 1A 2 13 4OE 1Y 3 12 4A 2OE 4 11 4Y 2A 5 10 3OE 2Y 6 9 3A GND 7 8 3Y (Top view) Absolute Maximum Ratings Item Symbol Ratings Unit Supply voltage VCC –0.5 to 7.0 V Input diode current IIK –50 mA Input voltage VI –0.5 to 7.0 V Output diode current IOK –50 mA VO Output current IO –0.5 to VCC +0.5 V –0.5 to 7.0 ±50 VI = –0.5 V VO = –0.5 V VO = VCC +0.5 V 50 Output voltage Conditions Output "H" or "L" Output "Z" or VCC: OFF mA VCC, GND current / pin ICC or IGND ±100 mA Storage temperature Tstg –65 to +150 °C 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.
