74ALVCH16244

74ALVCH16244 Low−Voltage 16−Bit Buffer with Bus Hold 1.8/2.5/3.3 V (3−State, Non−Inverting) The 74ALVCH16244 is an advanced performance, non−inverting 16−bit buffer. It is designed for very high−speed, very low−power operation in 1.8 V, 2.5 V or 3.3 V systems. The 74ALVCH16244 is nibble controlled with each nibble functioning identically, but independently. The control pins may be tied together to obtain full 16−bit operation. The 3−state outputs are controlled by an Output Enable (OEn) input for each nibble. When OEn is LOW, the outputs are on. When OEn is HIGH, the outputs are in the high impedance state. The data inputs include active bushold circuitry, eliminating the need for external pull−up resistors to hold unused or floating inputs at a valid logic state. Designed for Low Voltage Operation: VCC = 1.65 − 3.6 V 3.6 V Tolerant Inputs and Outputs High Speed Operation: 3.0 ns max for 3.0 to 3.6 V 3.7 ns max for 2.3 to 2.7 V 6.0 ns max for 1.65 to 1.95 V Static Drive: ±24 mA Drive at 3.0 V ±12 mA Drive at 2.3 V ±4 mA Drive at 1.65 V Supports Live Insertion and Withdrawal Includes Active Bushold to Hold Unused or Floating Inputs at a Valid Logic State IOFF Specification Guarantees High Impedance When VCC = 0 V† Near Zero Static Supply Current in All Three Logic States (40 mA) Substantially Reduces System Power Requirements Latchup Performance Exceeds ±250 mA @ 125°C ESD Performance: Human Body Model >2000V; Machine Model >200V Second Source to Indust...
