SN74LVTH16373DL .

产品概述

The SN74LVTH16373DL is a 16-bit transparent D Latch with 3-state outputs. It is designed for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers and working registers. It can be used as two 8-bit latches or one 16-bit latch. When the 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 OE input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without interface or pull-up components.
