描述 Description

The 74LVC374A is an 8-bit D-type positive edge-triggered flip-flop with 3-state outputs that is designed for 1.2V to 3.6V VCC operation. 
The device is provided with a clock (CP) input and an output enable (OE) input. When data at the Dn inputs suffices for setup and hold time purposes, data can be moved to the Qn outputs on the low-to-high clock transition. When OE is high, all outputs are in high-impedance state. OE has no influence on the state of the flip-flops. 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 74LVC374A is available in Green SOIC-20 and TSSOP-20 packages. It operates over an operating temperature range of -40℃ to +125℃.
