SN74ALVCH162841 具有三态输出的 20 位总线接口 D 类锁存器

This 20-bit bus-interface D-type latch is designed for 1.65-V to 3.6-V VCC operation.

The SN74ALVCH162841 features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. This device is particularly suitable for implementing buffer registers, unidirectional bus drivers, and working registers.

The SN74ALVCH162841 can be used as two 10-bit latches or one 20-bit latch. The 20 latches are transparent D-type latches. The device has noninverting data (D) inputs and provides true data at its outputs. While the latch-enable (1LE or 2LE) input is high, the Q outputs of the corresponding 10-bit latch follow the D inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs
