description
The ’AHC16240 devices are 16-bit buffers and
line drivers designed specifically to improve the
performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented
receivers and transmitters.
These devices can be used as four 4-bit buffers,
two 8-bit buffers, or one 16-bit buffer. They provide
inverting outputs and symmetrical active-low
output-enable (OE) inputs.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54AHC16240 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74AHC16240 is characterized for operation from –40
°
C to 85
°
C.
