MC74LCX573集成电路（IC）的锁存器规格书PDF中文资料

Low-Voltage CMOS Octal Transparent Latch Flow Through Pinout

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

The MC74LCX573 is a high performance, non–inverting octal transparent latch operating from a 2.7 to 3.6V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VIspecification of 5.5V allows MC74LCX573 inputs to be safely driven from 5V devices.
