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.
operation, but with the
CC
These devices are noninverting 16-bit buffers composed of two 8-bit sections with separate output-enable
signals. For either 8-bit buffer section, the two output-enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must
be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 8-bit
buffer section are in the high-impedance state.
