This 16-bit universal bus driver is designed for 1.65-V

Data

flow

from

A

to

Y

is

controlled

by

the

output-enable (OE) input. The device operates in the

transparent mode when the latch-enable (LE) input is

low. When LE is high, the A data is latched if the

clock (CLK) input is held at a high or low logic level. If

LE is high, the A data is stored in the latch/flip-flop on

the low-to-high transition of CLK. When OE is high,

the outputs are in the high-impedance state.

The outputs, which are designed to sink up to 12 mA, include equivalent 26-

Ω resistors to reduce overshoot and

undershoot.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
