Buffers, Drivers, Receivers, Transceivers FAQ

How does the latch enable (LE) input control data flow?

When LE is LOW, the A to Y data flow is transparent. When LE is HIGH and the clock (CP) is held steady, data is latched; data is stored in the flip-flop on the LOW to HIGH transient of CP.

What is the recommended configuration for the OE input during power-up?

To ensure a high-impedance state during power up or power down, the OE input should be tied to VCC through a pull-up resistor. The minimum resistor value is determined by the current-sinking capability of the driver.
