74HC374数据手册集成电路（IC）的触发器规格书PDF

描述 Description

The 74HC374 is an 8-bit D-type positive edge-triggered flip-flop with 3-state outputs that is designed for 2.0V to 5.5V VCC operation.
The device is provided with a clock (CP) input and an output enable (OE) input. When data at the Dn input suffices for setup and hold time purposes, data can be moved to the Qn output 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.
The clamp diodes of inputs allow the use of current limiting resistors to connect inputs to the voltage exceeding supply voltage.
The 74HC374 is available in Green SOIC-20 and TSSOP-20 packages. It operates over an ambient temperature range of -40℃ to +125℃.
