SN74LVC32373A 具有三态输出的 32 位透明 D 类锁存器
This 32-bit transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVC32373A is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be used as four 8-bit latches, two 16-bit latches, or one 32-bit latch. When 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 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
