74ALVT16373DL数据手册集成电路（IC）的锁存器规格书PDF

描述 Description

The 74ALVT16373 is a high-performance BiCMOS product designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V.
This device is a 16-bit transparent D-type latch with non-inverting 3-state bus compatible outputs. The device can be used as two 8-bit latches or one 16-bit latch. When latch enable (nLE) input is HIGH, the nQn outputs follow the date (nDn) inputs. When latch enable is taken LOW, the nQn outputs are latched at the levels of the D inputs one setup time prior to the HIGH-to-LOW transition.
