74VCX162373集成電路（IC）的鎖存器規(guī)格書PDF中文資料

General Description

The VCX162373 contains sixteen non-inverting latches with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. The flip-flops appear to be 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 VCX162373 is also designed with 26? resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceivers/transmitters. The 74VCX162373 is designed for low voltage (1.4V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74VCX162373 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
