Description

The SN74LVT16240 devices are 16-bit buffers and line drivers designed specifically for low-voltage (3.3-V) V_CC operation, but with the capability to provide a TTL interface to a 5-V system environment.

These devices SN74LVT16240 are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The devices SN74LVT16240 can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The devices provide inverting outputs and symmetrical active-low output-enable (OE) inputs.When V  is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down._CC However, to ensure the high-impedance state above 1.5 V, OE should be tied to V  through a pullup resistor; _CC the minimum value of the resistor is determined by the current-sinking capability of the driver.
