74HC373中文资料Octal D-Type Transparent Latch with 3-State Outputs数据手册SGMICRO规格书

描述 Description

The 74HC373 is an 8-bit D-type transparent latch with 3-state outputs that is designed for 2.0V to 5.5V VCC 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.
The clamp diodes of inputs allow the use of current limiting resistors to connect inputs to the voltage exceeding supply voltage.
The 74HC373 is available in Green SOIC-20 and TSSOP-20 packages. It operates over an ambient temperature range of -40℃ to +125℃.
