74ALVCH16240
Low-Voltage 16-Bit Buffer
with Bus Hold 1.8/2.5/3.3 V
(3State, Inverting)
The 74ALVCH16240 is an advanced performance, inverting 16bit
buffer. It is designed for very highspeed, very lowpower operation
in 1.8 V, 2.5 V or 3.3 V systems.
The 74ALVCH16240 is nibble controlled with each nibble
functioning identically, but independently. The control pins may be
tied together to obtain full 16bit operation. The 3state 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 pullup resistors to hold
unused or floating inputs at a valid logic state.
Designed for Low Voltage Operation: V
CC
= 1.65 to 3.6 V
3.6 V Tolerant Inputs and Outputs
HighSpeed 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
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
Second Source to Industry Standard 74ALVCH16240
To ensure the outputs activate in the 3state condition, the output enable pins
should be connected to V
CC
through a pullup resistor. The value of the resistor is
determined by the current sinking capability of the output connected to the OE pin.
