74LVC373A

The 74LVC373A is an 8-bit D-type transparent latch with 3-state outputs that is designed for 1.2V to 3.6V V_CC operation. 

The device is provided with a latch enable (LE) input and an output enable (OE) input. When LE is set high, data at the inputs gets access to the latches and the latches are transparent, the latch outputs will vary with corresponding data inputs. When LE is set low, the latches store data that appeared on the inputs for a setup time before the high-to-low transition of LE. When OE is high, all outputs are in high-impedance state. OE has no influence on the state of the latches. Both 3.3V and 5V devices can drive inputs, enabling this device to operate as translator in a mixed 3.3V and 5V system environment. All inputs support Schmitt-trigger action, which can allow the circuit to tolerate slower input rise and fall times.

 This device is highly suitable for partial power-down applications by using power-off leakage current (IOFF) circuit. When the device is powered down, the outputs are disabled, and the current backflow can be prevented from passing through the device. 

The 74LVC373A is available in Green SOIC-20 and TSSOP-20 packages. It operates over an operating temperature range of -40℃ to +125℃.
