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: V_CC = 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
• Static Drive:
6.0 ns max for 1.65 to 1.95 V
±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
• I_OFF Specification Guarantees High Impedance When V_CC = 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

†To ensure the outputs activate in the 3−state condition, the output enable pins
should be connected to V_CC through a pull−up resistor. The value of the resistor is
determined by the current sinking capability of the output connected to the OE pin.
