八路透明D类锁存器与三态输出 OCTAL TRANSPARENT D-TYPE LATCH WITH 3-STATE OUTPUTS
DESCRIPON/ORDERING INFORMATION
The SN74LVC373A octal transparent D-type latch is designed for 2.7-V to 3.6-V VCC operation. While the latch-enable LE input is high, the Q outputs follow the data D inputs. When LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs.
A buffered output-enable OE input can be used to place the eight outputs in either a normal logic state high or low logic levels or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pullup components.
OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
