SEMICONDUCTOR TECHNICAL DATA
Low-Voltage Quiet CMOS Octal Transparent Latch
(3-State, Non-Inverting)
The MC74LVQ373 is a high performance, non-inverting octal transparent latch operating from a 2.7 to 3.6V supply. The MC74LVQ373 is suitable for TTL level bus oriented applications where a memory element is required. The MC74LVQ373 contains 8 D-type latches with 3-state 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. The 3-state standard outputs are controlled by the Output Enable (OE) input. When OE is LOW, the standard outputs are enabled. When OE is HIGH, the standard outputs are in the high impedance state, but this does not interfere with new data entering into the latches. Current drive capability is 12mA at the outputs.
