description
These 16-bit buffers/drivers are designed specifically for low-voltage (3.3-V) V
capability to provide a TTL interface to a 5-V system environment.

CC
The devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The devices provide
noninverting outputs and complementary output-enable (OE and OE) inputs.
The outputs, which are designed to source or sink up to 12 mA, include equivalent 22-Ω series resistors to
reduce overshoot and undershoot.
