SN74ABT162841 具有三态输出的 20 位总线接口 D 类锁存器

These 20-bit transparent D-type latches feature noninverting 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The ’ABT162841 devices can be used as two 10-bit latches or one 20-bit latch. While the latch-enable (1LE or 2LE) input is high, the Q outputs of the corresponding 10-bit latch 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 (1OE\ or 2OE\) input can be used to place the outputs of the corresponding 10-bit latch in either a normal logic state (high or low logic levels) or a high-impedance state
