16-ch, 2.3-V to 3.6-V inverters with bus-hold, TTL-compatible CMOS inputs and 3-state outputs

The 'ALVTH16240 devices are 16-bit buffers/line drivers designed for 2.5-V or 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

These devices 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 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 VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, 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.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The SN54ALVTH16240 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALVTH16240 is characterized for operation from -40°C to 85°C.
