74LVTH16373MEA

低电压16位透明锁存器带3态输出 Low Voltage 16-Bit Transparent Latch with 3-STATE Outputs

General Description

The LVT16373 and LVTH16373 contain sixteen non-invert ing latches with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. The flip-flops appear transparent to the data when the Latch Enable LE is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable OE is LOW. When OE is HIGH, the outputs are in a high impedance state.

The LVTH16373 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
