Low-Voltage Quiet CMOS Octal Transparent Latch Flow Through Pinout
(3-State, Non-Inverting)
MC74LVQ573
The MC74LVQ573 is a high performance, non–inverting octal transparent latch operating from a 2.7 to 3.6V supply. The MC74LVQ573 is suitable for TTL level bus oriented applications where a memory element is required. 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., a latch output will change state each time its D input changes. When LE is LOW, the latches store the information that was present on the D inputs a setup time preceding the HIGH–to–LOW transition of LE.
