description

The ´LVT162240 is a 16-bit buffer and line driver designed for low-voltage (3.3-V) V_CC operation, but with the capability to provide a TTL interface to a 5-V system environment. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device provides inverting outputs and symmetrical (active-low output-enable) inputs.

The outputs, which are designed to source or sink up to 12 mA, include 22- series resistors to reduce overshoot and undershoot.

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

The SN74LVT162240 is available in TI's shrink small-outline (DL) and thin shrink small-outline (DGG) packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.

The SN54LVT162240 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74LVT162240 is characterized for operation from -40°C to 85°C.
