1. General description
The 74AUP1G373 provides the single D-type transparent latch with 3-state output. While the latch-enable (LE) input is high, the Q output follows the data (D) input. When pin LE is LOW, the latch stores the information that was present at the D-input one set-up time preceding the HIGH-to-LOW transition of pin LE. When pin OE is LOW, the contents of the latch is available at the (Q) output. When pin OE is HIGH, the output goes to the high-impedance OFF-state. Operation of input pin OE does not affect the state of the latch. Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 0.8 V to 3.6 V. This device ensures a very low static and dynamic power consumption across the entire VCC range from 0.8 V to 3.6 V. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
