!! #!
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.

1. These values of VI are used to test DC electrical characteristics only. Functional test should use VIH ≥ 2.4V, VIL ≤ 0.5V.
2. Incident wave switching on transmission lines with impedances as low as 75Ω for commercial temperature range is guaranteed. Maximum test
duration is 2ms, one output loaded at a time.

1. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGH–to–LOW (tOSHL) or LOW–to–HIGH (tOSLH); parameter
guaranteed by design.
