SN74AUC16373DGVR集成电路（IC）的锁存器规格书PDF中文资料

SN74AUC16373DGVR属于集成电路（IC）的锁存器。由德州仪器制造生产的SN74AUC16373DGVR锁存器锁存器是类似于触发器的基本数字存储设备，但是不同之处在于，在锁存使能（或类似命名）信号处于有效逻辑状态的任何时间，保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态，而相反的是，状态仅在保持状态已固定时改变。

DESCRIPTION/ORDERING INFORMATION

This 16-bit transparent D-type latch is operational at

0.8-V to 2.7-V VCC, but is designed specifically for

1.65-V to 1.95-V VCC operation.

The SN74AUC16373 is particularly suitable for

implementing buffer registers, I/O ports, bidirectional

bus drivers, and working registers. The device can be

used as two 8-bit latches or one 16-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. The high-impedance state and increased drive provide the capability to drive bus lines

without interface or pullup components.

OE does not affect internal operations of the latch. Old data can be retained or new data can be entered while

the outputs are in the high-impedance state.
