description

The ’AHCT16240 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 VCC through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54AHCT16240 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74AHCT16240 is characterized for operation from –40°C to 85°C.
