Low-Voltage CMOS Octal Transparent Latch Flow Through Pinout
With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting)
MC74LCX573
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 VI specification of 5.5V allows MC74LCX573 inputs to be safely driven from 5V devices. The MC74LCX573 contains 8 D–type latches with 3–state standard outputs. When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition, the latches are transparent, i.e.
