Low−Voltage CMOS 16−Bit Transparent Latch

With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting)

The MC74LCX16373 is a high performance, non−inverting 16−bit transparent latch operating from a 2.3 V to 3.6 V supply. The device is byte controlled. Each byte has separate Output Enable and Latch Enable inputs. These control pins can be tied together for full 16−bit operation. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX16373 inputs to be safely driven from 5.0 V devices.

M74LCX16373DTR2G属于集成电路（IC） > 锁存器。安森美半导体公司制造生产的M74LCX16373DTR2G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。
